Holo-Krome Critical Application Fasteners

When It Matters Most All Holo-Krome products are Made in the USA and used in a wide variety of market applications which demand high quality, high strength precision components. Since its formation in 1929, Holo-Krome has been at the forefront of fastener development and innovation. In 1930, Holo-Krome invented and later patented the first practical cold heading process for mass producing high tensile strength alloy steel socket screws. As you browse through our 2010 catalog, you will see Holo-Krome manufactures and stocks a full line of standard, high quality socket screw products. In addition to the standard product line, Holo-Krome manufactures semi-standards, special fasteners and cold headed parts. With emphasis on lower cost and higher productivity, more companies are looking to Holo-Krome to solve assembly and “tough-to-manufacture” part problems. If there is a length, coating, or other criteria you don’t find on our website or in our catalog, we will supply a quotation. We use our 80 years of fastener manufacturing knowledge to shape metal by carefully controlling metal forming temperatures that yield inherently stronger parts. The metal is reinforced in critical stress areas eliminating the possibility of tears so common with machined parts. Holo-Krome can form various types of materials including aluminum, brass, austenitic and martinsitic stainless, 4000 series alloys, H-11 and other tool steels into difficult shapes and improve the material grain flow that is not achievable with machining processes. For some

parts, tensile and shear strength properties are increased from a machined version. Tough-to-manufacture parts can be produced at less cost than traditional manufacturing methods. With little to no metal removal, material savings frequently justifies Holo-Krome’s heading process. Holo-Krome’s vertically integrated manufacturing processes encompass many innovative secondary and finishing operations such as high speed/proprietary machining, contour grinding and precision roll threading up to 1-1/2" diameter. Holo-Krome’s finishing operations include state of the art controlled-heat treating equipment and full metallographic inspection capabilities. Most high strength alloy parts are conveyed through automated furnaces to insure specified metallurgical properties are achieved. We also can provide Black Oxide coating.

Benefits • Traceability.

Each fastener has its own quality control number tracing it all the way back to the steel mill.

• The highest torque/

clamping force available in the entire industry.

• Roll threading, not thread cutting, for stronger, more precise radiused root and run-out threads for increased fatigue life.

• Technical support for those

tough questions for design and applications engineers — over the phone or on-site.

• The most complete line of

fasteners in the business in both inch and metric sizes.

The most expensive fasteners.The failures. Fasteners that fail to live up to the manufacturer’s or importer’s claims. Fasteners that save a few pennies initially, but end up costing hundreds, maybe even thousands of dollars in replacement costs. Fasteners of unknown origin that don’t carry a manufacturing pedigree. Fasteners that can even cost you your priceless reputation. Fasteners without the unmistakable Holo-Krome brand.

Second most expensive fasteners.But what they lack in strength, can usually be made up in numbers. So, drill more holes, use more and larger fasteners, and the chances are pretty good that everything will hold together. That is, everything but your budget. Here’s why...

When determining total fastener cost, studies show that the per unit price of a given fastener represents only approximately 18% of its total in-place cost. The other 82% covers drilling, tapping, and assembly steps. The real money is saved by using fewer, stronger fasteners. Before you buy imported, or bargain priced fasteners, consider the overall cost figure, and discover where the real value lies.

Third most expensive fasteners.• Precision 3A threads for greater clamping force.• Radius root and radius run-out threads for structural integrity.• Controlled fillets for uniform loading under the head.• Technical support to assist in solving fastening problems.• Value added services from over 300 distributors nationwide. • Inspection at controlled intervals — Filing of test data for long term traceability, long term reliability.

When you consider the less expensive, higher risk alternative,Holo-Krome is the real value. Often the least expensive fastener.

The most expensive fastener anyone can buy is one that fails. The next most expensive fastener is one that saves a few pennies on price, then takes them all back by adding dollars to your in-place costs. Next comes

Holo-Krome precision fasteners with greater endurance and fatigue life. They

do a better job than ordinary fasteners. Because, unlike fasteners of unknown

origin, ours come with more than 75 years of specialized engineering support; manufactured, tested and certified in our Connecticut Facility.

The World’s Third Most Expensive Fastener.

RS Definitions of Screw and Thread Terms

Screw Thread - A ridge or uniform section in the form of a helix on the external or internal surface of a cylinder, or in the form of a conical spiral on the external or internal surface of a cone.

External Thread - An external thread is a thread on the outside of a member.

Internal thread - An internal thread is a thread on the inside of a member.

Major Diameter - The largest diameter of the thread of the screw or nut. The term "major diameter" replaces the term "outside diameter" as applied to the thread of a screw and also the term full diameter as applied to the thread of a nut.

Minor Diameter - The smallest diameter of the thread of a screw or nut. The term "minor diameter" replaces the term "core diameter" as applied to the thread of a screw and also the term "inside diameter" as applied to the thread of a nut.

Pitch Diameter - On a straight screw thread, the diameter of an imaginary cylinder, the surface of which would pass through the threads at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the cylinder. On a taper screw thread, the diameter, at a given distance from a reference plane perpendicular to the axis of an imaginary cone, the surface of which would pass through the threads at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the cone.

Pitch - the distance from a point on a screw thread to a corresponding point on the next thread measured parallel to the axis.

The pitch in inches -

1Number of threads per inch

Half Angle of Thread - The angle included between a side of the thread and the normal to the axis, measured in an axial plane.

Angle of Thread - The angle included between the sides of the thread measured in an axial plane.

Helix Angle - The angle made by the helix, or conical spiral, of the thread at the pitch diameter with a plane perpendicular to the axis.

S

Crest - The surface of the thread corresponding to the major diameter of the screw and the minor diameter of the nut.

Lead - The distance a screw thread advances axially in one turn. On a single threaded screw the lead and pitch are identical; on a double threaded screw the lead is two times the pitch; on a triple threaded screw the lead is three times the pitch, etc.

Root - The surface of the thread corresponding to the minor diameter of the screw and the major diameter of the nut .

Side or Flank - The surface of the thread which connects the crest with the root.

Axis of a Screw - The longitudinal central line through the screw.

Base of Thread - The bottom section of the thread; the greatest section between the two adjacent roots.

Depth of Thread - The distance between the crest and the base of the thread measured normal to the axis.

Number of Threads - The number of threads in one inch of length.

Length of Engagement - The length of contact between two mated threaded parts measured axially.

Depth of Engagement - The depth of thread contact of two mated parts, measured radially.

Pitch Line - An element of the imaginary cylinder or cone as specified under "Pitch Diameter".

Thickness of Thread - The distance between the adjacent sides of the thread measured along or parallel to the pitch line.

Mean Area - The term "mean area of a screw," when used in specifications and for other purposes, designates the cross-sectional area computed from the mean of the basic pitch and minor diameters.

Terms Relating to Classification and Tolerances

Allowance - An intentional difference in the dimensions of mating parts. It is the minimum clearance of the maximum interference which is intended between mating parts. It represents the condition of the tightest permissible fit, or the largest internal member mated with the smallest external member.

Examples:

A 1/2-13 American National Coarse Thread.

Minimum pitch diameter of nut (2B)...............0.4500Maximum pitch diameter of screw (2A) ........ .4485

Allowance (positive).......................................0.0015

Tolerance - The amount of variation permitted in the size of a part.

Example:

1/2 - 13, 3A American National Coarse Thread Series.

Maximum pitch diameter ...............................0.4500Minimum pitch diameter ................................ .4463

Tolerance .......................................................0.0037

RS Basic Size - The theoretical or nominal standard size

from which all variations are made.

Crest Clearance - Defined on a screw form as the space between the crest of a thread and the root of its mating part.

Finish - The character of the surface on a screw thread or other product.

Fit - The relation between two mating parts with reference to the conditions of a assembly. For example: Wrench fit; close fit; medium fit; free fit; loose fit. The quality of fit is dependent upon both the relative size and the quality of finish of the mating parts.

Neutral Zone - A positive allowance (See "Allowance.")

Limits - The extreme permissible dimensions of a part.

Example :

1/2-13, Class 3A, American National Coarse Thread Series.

The limits are:

Maximum pitch diameter (3A)........................0.4500Minimum pitch diameter (3A) ........................0.4463

The Holo-Krome Company has been a leader in the Socket Screw industry for over 80 years.

In 1930, we developed and later patented the first practical cold heading process for mass producing high tensile alloy steel socket screws.

Today, virtually all products of that nature are manufactured by one or more of the methods developed by Holo-Krome.

With only slight changes in shape or dimensions, we are able to head many parts that previously took a screw machine to produce — and are doing it at a significant savings.

Eight Decades of Excellence

When fastener talk turns to quality, one brand is mentioned without fail: Holo-Krome. And little wonder, for Holo-Krome fasteners have been performing in some pretty tight spots, under tremendous pressures, for years, even decades, without fail. How? The answer is simple. There is no compromising when it comes to quality. None.

Unfailing Fasteners

Benefits • Traceability.

Each fastener has its own quality control number tracing it all the way back to the steel mill.

• The highest torque/clamping

force available in the entire industry.

• Roll threading, not thread cutting, for stronger, more precise radiused root and run-out threads for increased fatigue life.

• Technical support for those

tough questions for design and applications engineers — over the phone or on-site.

• The most complete line of

fasteners in the business in both inch and metric sizes.
