KEEljSERT@ Inserts Installation Guidelines

1.

2.

3.

4.

Edge Distance

Boss Diameter: 1 l/2 x O.D. of insert.

Edge distance to a fiat side: Can be as little as l/32 over l/2 O.D. of the insert. Tap marks may show on flat side and the insert should be positioned with kees 45” to 90” (2 kees).

Broaching

General material harder than RC 30 may require that the tapped holes be broached for the kees. Aluminum, anodized after tapping, also may require broaching. Broach blades may not stand up for more than 3 or 4 holes when broaching inconel and similar alloys. It is possible to drive kees of the KNH and KNHXH series in harder material than the KN series because of wall collapse. Tools with threads to support the inside of the insert are available if wall collapse is encountered.

Thickness of Parent Material

Miniature KEENSERTS Inserts - .015 (minimum) thicker than the length of the insert if it is undesirable to have it protrude through underside of panel. “T” (dimension from catalog) + ,015 if protrusion through underside is permissible.

KN, KNH and KNHXH KEENSERTS Inserts - General minimum thickness should be equal to bolt diameter (Tridair Engineering should be consulted for these applications). Insert will protrude through bottom surface unless length is coded.

Internal Thread Lock

All our internal thread locks conform to MIL-N-25027.

MIL-N-25027 does not call for seating the bolt.

We test with minimum P.D. 3A bolts. 2A bolts, being smaller, will provide very little or no torque and should not be used. Bolts should have 4 turns after encountering the lock. Less turns may not provide the required torque and more turns will wear out the lock faster. For a metric thread a 4H Class bolt is used. to test locking feature.

Seating the bolt will affect the locking torque and the number of locking cycles. How it will be affected depends on the material of the bolt and the insert, the finish on bolt and insert, lubrication on the threads and under the head of the bolt, and the seating torque.

5. Standard Minor Diameter Versus Modified Minor

All other things being equal standard minor diameters will provide greater shear engagement areas. This would be desirable where a bolt goes directly into a tapped hole. In the case of inserts where the O.D. of the insert is so much larger than the diameter of the bolt being used, using a larger tap drill, as we do, does not lower the pullout values to any great extent.

~EEhJSERTS@INSERTS AND STUDS

KEENSERTS Inserts-and Studs provide strong, perma sizes, lengths, materials and types. Because of our nent, metal threads in virtually any material - ferrous, years of application experience, we are geared to non-ferrous or non-metallic. provide solutions to all types of special insert pro-

- blems. If your don’t see a design in this catalog that

Tridair pioneered the design of this type of insert and will suit your application, consult our Sales Engineer is able to offer the widest available choice of standard for other designs to meet your specific needs.

Positive mechanical lock against rotation.

KEES are driven down into the tapped threads of the parent material during installation to securely lock the insert against rotation.

Featuring an exclusive external thread design, KEEYSERTS pro- vrde maximum pull-out strength wrth a minrmum outsrde diameter.

n Installed with standard taps and drills.

w Available from stock in many sizes and types.

Securely

locked

against rota/ion.

Internal thread lock feature available. inserts wrth this feature are desrgned to securely lock a bolt when It is entered Into the Insert only a few turns. The lockrng torque values are consistent and well wrthrn the range established by MIL-I-45914A Even after repeated installations and remov als of the bolt, the lock maintains sufficient locking torque to prevent the bolt from vrbratrng out.

PULL-OUT STRENGTH (for Reference Purposes Only)

To compute the Pull-Out Strength in any parent material, use the following formula:

Calculated Minimum Shear Minimum Ultimate

Pull-Out Strength = Engagement X Shear Strength of

Area (IN*) the Parent Material (PSI)

ABOUT SHEAR ENGAGEMENT AREA

Catalog values for shear engagement areas are based on shear failure in the parent material when the parent material is significantly weaker than the insert or stud material. Such failure occurs in the parent material at or near the

n- major diameter of the insert or stud end external thread. For parent materials of hardness similar to that of the insert or stud, failure occurs by combined shear of both materials simultaneously and will occur along a surface approaching the pitch line. The calculated shear engagement area should be reduced accordingly. For sufficiently hard parent materials, failure may occur by thread shear at the internal thread of the insert or by stud nut end thread failure.

NOTES:

Inserts: MIL-I-45914, as amended 25Nov1970 has been superseded by MIL-I-45914A dated 25Apr1991. Any reference to MIL-N-25027 is to be disregarded. The tests and methods are all covered in MIL-I-45914A.

Studs: MIL-S-45915 dated 25Nov1970 has been superseded by MIL-S-45915A dated 21Aug1991

Using the installation tool, drive in the KEES. The tool may be used with a hammer or held in an arbor press. The correct insert tool is tabulated with each type of insert in this catalog.

n For Miniature Series inserts, screw the insert onto the threaded mandrel and turn the insert into the tapped hole.

. When the tool handle is depressed, a special spring- loaded trip mechanism within the tool will drive the KEES into the parent material.

n The replacement of inserts is accomplished without reworking the parent material, and the same size insert is used in the original hole.

GENERAL PURPOSE INSERTS iii 3

Inserts shown In this section were designea for general purpose applications.

The Miniature size inserts are for use in electronic and aerospace applications where size and strength are critical. These inserts may be installed in sheet material as thin as 1 /I 6” providing protrusion of insert is not objectional. Their pull-out strength exceeds the tensile strength of most Military Standard screws. The Internal Thread Locking versions conform to MIL-N-25027.

Lightweight, Heavy Duty and Extra Heavy Duty inserts are offered in a wide choice of thread diameters and materials to suit virtually any performance requirement. Each is available with Internal Thread Locking features.

Carbon Steel inserts are for use In commercial or repair applications where NAS or MS specifications are not required.

Internal thread sizes larger than shown are available upon request.

SPECIFICATIONS:

All dimensions in inches.

Tolerances for all inserts in this section are + .OlO unless otherwise specified.

Other materials available upon request.

Shear engagement area dimensions shown (sq. in.) are minimums.

NOTE: All internal threads are manufactured to MIL-S-8879 except where noted.

inserts wifh internal thread size 5/16 and above furnished with 4 locking KEES.

Material: Cl215 Steel or equivalent.

Finish: Parkerize. 16 F&child Fasteners

SPECIAL PURPOSE INSERTS

Floating Inserts are desrgned to compensate automatically for misalignment from ,015 (for 2-56) up to .040 (for #IO and larger sizes). The floater is supplied as a one-piece unit. Ideal for use on curved surfaces or for use with flathead screws.

Blind End Inserts are used in applications where it is important to keep a screw isolated from certain assemblies, such as electronic circuitry. They assure that dust, chips and other foreign objects will not contaminate an assembly.

Hydraulic Inserts are for use in hydraulic or fuel systems. They offer strong, permanent threads and wear-resistant sealing surfaces in soft metal castings or accessories. They permit repeated installation and removal of AND and MS fittings without-damage to expensive castings and ports.

_ High-Strength Aluminum Inserts, designed for miniaturized space and electronic systems, may be used in most any material. including aluminum and magnesium. A significant reduction in weight can be realized with these non-magnetic inserts. They may be installed in materials as thin as l/8“ (l/16” if end may protrude).

Solid Inserts are ideal for relocating holes that have been drilled or tapped in the wrong location, to fill holes that are too large, or to salvage expensive castings.

Cast-In Inserts are designed for casting into place during die casting, centrifugal, investment and permanent mold processes and many plastic molding operations. Their high strength resists

- high oressures generated during these processes.


SPECIFICATIONS: Tolerances for all inserts in this section are + ,010 unless otherwise specified. Shear engagement area dimensions shown (sq. in.) are minimums.

Installation:

Studs are installed in the same manner as described for inserts. However, the installation tool for the studs has a hole to receive the stud. To remove a stud, simply cut off the nut end at a point just above the

surface. A drill bushing will be required for removal drill. Removal is the same as for inserts. The same size replacement stud may be installed in the original hole. Strength of the replacement is equal to that of the original.

Heavy Duty Series AND Standards

32 SPECIFICATIONS:

All dimensions in inches.

Tolerances are + ,010 unless otherwise specified.

Shear engagement area dimensions (sq. in.) shown are minimums.

Studs with nut end thread size 5/16 and larger are furnished with 4 locking KEES

If ordering nut end length equal to or shorter than nut end thread length, then nut end will be fully threaded to within 2-l/2 pitches of shoulder.

Nut end threads are fully formed by a single rolling process subse- quent to heat treatment and prior to plating.

Drilled hole in nut end is optional on all studs except AND standard parts.


Consult home office or local sales engineer about installation tools to be used with studs having nut end lengths greater than maximum specified for standard tools.

NOTE: Nut end threads are manufactured to MIL-S-8879 except where noted.

cn m c) d Self-Broaching 9 KEENSERTS” Inserts and Studs. - -

Design and Features Rexnord Specialty Fastener Division pioneered the design of permanent, wear-resistant, threaded inserts and studs which feature a positive mechanical lock against rotation, The high-performance, self-broaching KEENSERTS inserts and studs shown in this catalog are designed to dramatically reduce time and labor required for installation into hard or tough aerospace parent materials, Precision-treated 400 series corrosion resistant steel locking KEES “self-broach” into parent materials, eliminating broaching tools, saving time, labor and considerable costs.

Standard KEENSERTS inserts and studs install easily into soft materials, such as magnesium and aluminum. The KEE “self-broaches” these materials, thus providing a positive lock against rotation. However, hard or tough materials such as 17-4 PH CRES, INC0718 or titanium require an additional installation step of broaching the keeways using a broaching tool. This “prebroaching” procedure is time-consuming, expensive and sometimes frustrating.

Self-broaching KEENSERTS inserts and studs feature a KEE configuration and material that broaches hard parent materials which previously required the “prebroaching” step. The result is a fast, efficient method for installing inserts or studs in parent materials with a Rockwell hardness in excess of Rc 40.

The pre-positioned KEES automatically set the insert or stud at the proper depth below the surface of the parent material. Unlike conventional inserts, there is no need to maintain critical depth tolerances, and no chance of inadequate locking or deformation of internal threads due to miscalculations of depth.

Features: l Positive mechanical lock against rotation

KEES are driven down into 1116

tapped threads of the parent mate/is/ durmg mstaiiaiion to

secure/y ioch the insert against relation.

l Hole prepared with standard taps and drills. l Installs in seconds withTridair power installation tool. l Available in many sizes in heavy duty and extra heavy

duty configuration. l Meets the following configuration specifications:

MS51831, MS51832, MS51833 and MS51834 series. l Internal thread locking feature meets the reauirements

of MIL-I-45914 l Exclusive external thread desrgn provides maxrmum

pull-out strength with a minimum outside diameter

il. Align KEES to keeways.

12. Drive KEES.

13. Remove installatron tool.

14. Replace blades in broaching tool as required (one to three cuts per blade in INC0718 material is common).

Removal (If removal is necessary follow these simple steps.)

inserts

Studs To remove a stud, simply cut off the nut ena at a pornt just above the surface.

Removal is the same as for Inserts, except a drill bushing will be required to align removal drill. The same size replacement stud may be installed in the original hole. Strength of the replacement is equal to that of the original.

1. Use standard drill to remove insert material between KEES.

2. Deflect KEES inward and break off.

3. Remove insert with E-Z out type tool.

4. An identical insert can now be installed in the original hole. No re-work of the hole will be necessary.

Special Note: that of the insert or stud, failure occurs by combined shear of Catalog values for shear engagement areas are based on both materials simultaneously and will occur along a surface

n shear failure in the parent material when the parent material is approaching the pitch line.The calculated shear engagement significantly weaker than the insert or stud. Such failure area should be reduced accordingly. For sufficiently hard occurs in the parent material at or near the major diameter of parent materials, failure may occur by thread shear at the the insert or stud. For parent materials of hardness similar to internal thread of the insert or by stud nut end thread failure.

Spark Plug Insert Kit-

Inserts in these kits are designed for use in the repair or modifi cation of spark plug threads in many types of cylinder heads. 14mm spark plug inserts can be used with most types of spark plugs, tapered seat as well as gasket seat. n Manufactured from a high-strength aluminum alloy, only&Ef~SERTS inserts will operate as cool as the original condition. Cooler operation means better performance, increased plug life and reduced emissions. W Sealing washers are also included in each kit. They provide a positive seal to prevent the escape of gas from the combustion chamber. Each master kit includes complete instructions and tools for installation. Refill kits are available to replenish the master kit.

Notes: 1. Grade 5 bolt values.

2. Data from engineering report No. 2112. 3. Test conducted in 2024.T4 aluminum. 4. Test from engineering report No. 931 I. The IO-32 size

used was a 160,000 psi bolt. The other bolts were grade 8. F.S. = test stopped.

IIS data IS based upon torque loads necessary to Jevelop approximately 75% of the proof loads of a cadmium plated grade 8 bolt. It assumes the insert is in an aluminum or steel with a 37,000 psi shear strength. Should the torque tension relationship be critical, the user should conduct tests to determine the proper values to use.

6. The “KN” and “KNH” series inserts are made of 303 stainless. The configuration is the same as the “RKKA” or “RKK” inserts shown in this catalog, except the KNH813J has an 1 l/l 6-I 1 NS external thread.

LEES

These new Tridair Self-Broaching _KEEtjSERTS’$ Inserts have a Vespel SP polymide resin locking element to provide an interference fit with the bolt at the time of assembly. The Vespel material allows for high temperatures and multiple reuse. They have been tested to 600°F. with an INCO 7-18 bolt loaded to 120 KSI stress for 6 hours. And, after fifty repeated tests the minimum breakaway torque of the insert was still within the values of MIL-I-45914 and other applicable specifications.

The 420 CRES KEES ease installation Into parent materials with Rockwell hardness of Rc44 or less.

Tridair” Self-Broaching KEENSERTS” Inserts - with Vespel” Locking Element Typical Hole Preparation

lao_ 82’

Hole Preparation: 1. Locate and drill with standard drill to “A” Dia.

2. Countersink with standard countersink (82” to IOO’), to “B” Dia

3. Tap with a standard tap to produce thread form “T.”

Insert Installation: 1. Start the tool by depressing the Air Supply Lever. This will rotate the threaded mandrel in a clockwise direction. Place the top end of the KEENSERT against the rotating mandrel and thread it on (Figure 1).

2. With the loaded tool rotating clockwise (Air Supply Lever depressed), place the KEEijSERT against the threaded hole in the part and allow it to screw in (Figure 2). Take care to align the tool with the axis of the hole. When the insert is at the correct depth the shoulder on the nosepiece will contact the part and stall the tool. Remove hand from Air Supply Lever.

3. Drive KEES by pushing KEE Drive Button (Figure 3).

4. Back the tool out by first depressing the Reverse Button and then the Air Supply Lever. Release the button after the tool is out.The tool is now ready to be loaded for the next installation (Figure 41.

5. Tool Inlet Pressure The 70950-6 power tool has automatically Installed self-broaching KEENSERT inserts and studs into materials such as A286, lnconell 718. Hastoloy X, 17-4 PH and trtanium.

Since the 420 CRES KEE acts as a cutting tool, each application using the self- broaching KEENSERT should allow for some test samples of the material used in production to determine actual minimum pressure required.

Typical Pressure Settings Reqwed: c*.,n-,{ ~;;;;;;Eysure to266 go-100 PSI 26 6 to 34.3 100-125 PSI 34 3 to 43.1 125-150 PSI I

6. Axis of hole to be normal to entry surface or provide spotface when required

Removal (if required follow these simple steps):

1, Use standard drill to remove insert material between KEES (see table above).



4. An identical insert can be installed in the original hole. No re-work of the hole is necessary. Strength of the replacement is equal to that of the original.
