Load Tables
Screw Shear and Tension Strengths
- 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.
- 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.
- 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
- Values are based on steel members with a minimum yield strength of Fy = 33 ksi and tensile strength of Fu = 45 ksi.
- The values for 16 ga., 18 ga., 20 ga. and 22 ga. are based on tests per AISI Standard Test Method S905-08.
- The safety factor Ω and resistance factor Φ used to determine the ASD and LRFD strengths are based on AISI S100, Chapter F.
- The values for 16 ga., 18 ga., 20 ga. and 22 ga. are based on the calculations per AISI S100-07, Section E4.
- 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
- Values are based on calculations per Section E4 of AISI S100-07.
- The tabulated ASD and LRFD loads are based upon a safety factor Ω of 3.0 and the resistance factor Φ of 0.5.
- For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.
