    These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated woods. For applications in higher-exposure applications, consider type-300 series stainless-steel fasteners for superior corrosion resistance. See additional important information before selecting a fastener for a specific application.

Load Tables

X Metal Screw — Cold-Formed Steel Connection Loads

  1. Screws and screw connections have been tested per AISI Standard Test Method S904-08 and S905-08 with the exception of 22 gauge values which are based on calculations of the AISI S100-07 Section E4.
  2. The tabulated ASD and LRFD allowable loads for cold-formed steel (CFS) members are based on the lower of the screw strength or the strength of the screw in the connected members per AISI S100-07.
  3. The safety factor Ω and resistance factor Φ used to determine the ASD and LRFD strength are based on AISI S100-2007 Section F.
  4. The nominal strength values listed are achieved under laboratory conditions and should not be used for design loads.
  5. Values are based on CFS members with a minimum yield strength of Fy = 33 ksi and tensile strength of Fu = 45 ksi for 43 mil (18 ga.) to 27 mil (22 ga.), minimum yield strength of Fy = 50 ksi and Fu = 65 ksi for 54 mil (16 ga.) to 97 mil (12 ga.), and a minimum yield strength of Fy = 36 ksi and Fu = 58 ksi for 1/8" and thicker.
  6. For design purposes, steel sheet thicknesses are 0.0283" for 27 mil, 0.0346" for 33 mil, 0.0451" for 43 mil, 0.0566" for 54 mil, 0.0713" for 68 mil, and 0.1017" for 97 mil. The actual sheet thickness shall not be less than 95% of these design thickness as specified in AISI S100-7 Section A2.4.
  7. Screw diameters per AISI S207-07 General Provisions Commentary Table D1-1.
  8. Minimum required screw length is the lesser of 3/4" or the minimum length required for the screw to extend through the steel connection a minimum of 3 exposed threads per 2004 AISI General Provisions Standard section D1.3.
  9. Screw head or washer diameter, dw, for #10 and #12 screws is 0.398".
  10. The allowable load (ASD) values showing are not permitted to be increased for short duration loads such as wind or earthquake loads.
  11. The lower of the pull-over and pull-out allowable load should be used for tension design.
  12. The tabulated shear values are based on the thinner steel member in connection. Steel thickness for both member must be in the range of 1/2" - 22 gauge.
  13. The XQ-S1224 screws are recommended for 16 gauge and thicker steel.
  14. See General Load Tables for information on screw strength.

Screw Shear and Tension Strengths

  1. Pss and Pts are nominal shear strength and nominal tension strength for the screw itself, respectively, and are the average (ultimate) value of all tests determined by independent laboratory testing.
  2. The ASD and LRFD loads for tension are calculated using a safety factor Ω of 3.0 and the resistance factor Φ of 0.5, respectively.
  3. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.

Structural Screw Pull-Over Strength with Steel Minimum Yield Strength Fy = 33 ksi

  1. Values are based on steel members with a minimum yield strength of Fy = 33 ksi and tensile strength of Fu = 45 ksi.
  2. The values for 16 ga, 18 ga, 20 ga and 22 ga are based on tests per AISI Standard Test Method S905-08.
  3. The safety factor Ω and resistance factor Φ used to determine the ASD and LRFD strengths are based on AISI S100, Chapter F.
  4. The values for 16 ga, 18 ga, 20 ga and 22 ga are based on the calculations per AISI S100-07, Section E4.
  5. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.

Structural Screw Pull-Out Strength

  1. Values are based on calculations per Section E4 of AISI S100-07.
  2. The tabulated ASD and LRFD loads are based upon a safety factor Ω of 3.0 and the resistance factor Φ of 0.5.
  3. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.
