FCB Bypass Framing Fixed-Clip Connector
The FCB clip is an economical, high-performance fixed-clip connector that can be used for a variety of framing applications. It is rated for tension, compression, shear and in-plane loads and offers the Designer the flexibility of specifying different screw and anchorage patterns that conform to desired load levels.
Features:
• Rated for tension, compression, shear and in-plane loads
• Provides design flexibility with varying screw and anchorage patterns that achieve different load levels
• Strategically placed stiffeners, embossments and anchor holes maximize connector performance
Material: 54 mil (16 ga.)
Finish: Galvanized (G90)
Installation:
• Use the specified type and number of anchors.
• Use the specified number of #12 self-drilling screws to CFS framing. Note that #10 self-drilling screws can be used per the load tables given on pp. 54, 55.
Codes: See p. 11 for Code Reference Key Chart

1. Min. fastener quantity and load values — fill all round holes; max. fastener quantity and load values — fill all round and triangular holes.2. Allowable loads are based on clip capacity only and do not consider anchorage. The capacity of the connection system will be
the minimum of the tabulated value and the allowable load from the FCB Allowable Anchorage Loads table on p. 49.3. Anchorage to the supporting structure using welds or a minimum of (2) #12–24 self-drilling screws is required.4. Allowable loads are based on in-plane loads applied to the stud fasteners that are nearest the support with complete
rotational restraint at the studs. For a more extensive treatment of in-plane loads please refer to Simpson Strong-Tie engineering letter L-CF-CWCF1DIR17 at strongtie.com.
5. Reference pp. 54, 55 for loads for #10–16 screws. 6. Reference pp. 63–67 for LRFD design strengths.

1. For additional important information, see General Information on p. 16.2. Allowable loads are for clip anchorage only. The capacity of the connection system will be the minimum of the tabulated allowable
anchorage loads the allowable load from the FCB Allowable Connector Load table on p. 48. 3. Allowable loads for #12–24 self-drilling screws and PDPAT powder-actuated fasteners are based on installation in minimum 3/16"-thick
structural steel with Fy = 36 ksi. PDPAT values are also provided for A572 steel. Values listed above maybe used where other thicknesses of steel are encountered provided that the fastener has equal or better tested values into thicker steel (see p. 16). It is the responsibility of the Designer to select the proper length fasteners based on the steel thickness installation.
4. For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete is suggested. For predrilling use a maximum 3/16"-diameter drill bit.

FCB Supplemental Information
The following FCB supplemental information is given to help Designers with value-engineered solutions for our FCB connectors. Loads are given for fastener patterns other than our standard “min.” (fill all round holes) and “max.” (fill all round and triangle holes). In addition, the tables give LRFD loads and loads for #10 screws as well as #12 screws.

FCB Supplemental Information
Footnotes for Tables 2, 3, 4 and 51. Calculated values are per AISI RP15-2, AISI S-100, or generally accepted industry standards.
Shaded values for #12–14 screws are tabulated in this catalog and are based on testing per ICC-ES AC261. For #12–14 screws unshaded tabulated values are conservatively based on the maximum value from calculations and from the minimum (4-screw) tested values.
2. The tabulated values do not account for anchorage to the support. Anchor strength must be calculated separately and may reduce the capacity of the connection when compared to the tabulated values.
3. Tabulated values do not include shear, web crippling, buckling or other local effects in the member. The Designer must check member limit states separately.
4. For load combinations that include F1 and/or F2 and/or F3, use an appropriate interaction equation.
5. #10–16 screws shall have Pss ≥ 1,620 lb. #12–14 screws shall have Pss ≥ 2,520. Calculated values are per AISI S-100. Screws must be installed with three (min.) exposed threads.
6. The number of screws listed is for one clip leg that is attached to the supported stud.
7. For the minimum screw pattern, fill all round holes. For the maximum screw pattern fill all round and triangle holes. Reference Table 1 on p. 50.
8. Reference p. 48 for load direction definitions.
9. In addition to calculations of net and gross section tension, and screw shear of the clip leg attached to the stud, F2 values are also calculated for weak-axis bending of the anchored clip leg with the line of bending at the holes farthest from the bend radius of the angle. The Designer is responsible for calculating pull-over, pullout and tension strength of the anchors and this may reduce F2 strength compared to the tabulated values.
10. F3 values are computed using the plate buckling provisions of AISI RP15-2.
11. For the F4 values it is assumed that all of the connection eccentricity is taken by screws in the supported stud. F4 values are also limited by plate shear buckling per AISI RP15-2. The Designer is responsible for calculating the shear capacity of the anchorage which may reduce F4 strength compared to the tabulated values.
12. In addition to the limit states given in notes 9, 10 and 11, F2, F3 and F4 are also limited by screw shear according to the thinnest connected part of the connector and stud.
13. Where test data is not available, service load limits for F2 and F3 are not given since there are no generally accepted industry methods available to compute these values. Calculated F4 service load limits are based on AISI Research Report RP15-2 for 1⁄8" deflection.
14. For 50 ksi studs, 68 mil (14 ga.) and thicker, use tabulated values for 54 mil (16 ga.) — 50 ksi studs.

Connectors for Cold-Formed Steel Construction

Supplemental Information for Slide-Clip and Rigid Connector
Does your project require DoD-compliant blast design?Although Allowable Strength Design (ASD) is widely used by Designers of Cold-Formed Steel (CFS) construction, some projects require additional connector limit states beyond the typical ASD values that are normally tabulated in our load tables. For example, many Department of Defense (DoD) projects require blast design of exterior wall framing and connections. Such projects may require the LRFD strength or nominal strength for the blast calculations. For a more comprehensive background on blast design please reference the Simpson Strong-Tie® Structural Engineering Blog at seblog.strongtie.com and enter the search term “DoD”.

1. Tabulated values are for the connector and attachment to the stud-wall framing. The assembly strengths are the minimum of those listed and the anchorage values listed in Table 5 on p. 66.
2. Service Load Limit is the load at 1⁄8" deflection for use in evaluating the performance under service-level loads.3. LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.4. Nominal Strength is defined in AISI S100-07.
