Strong-Drive® XL LARGE-HEAD METAL Screw
On This Page
Product Details
Strong-Drive XL Large-Head Metal screws are load tested and code listed, allowing you to get the maximum load values for installation. These screws are the perfect choice when high shear or uplift resistance is required and can be excellent 1-for-1 replacements for pins.
Key Features
- 5/16" hex drive (replacement driver bit — BITHEXR516-134)
- #5 drill point
- Quik Guard® coating
- 5/8" diameter integral washer
- US Patent 9,518,599
Applications
- Steel decking or other cold-formed steel framing; connectors to structural steel
Warning
- Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, use this product in dry, interior and noncorrosive environments only.

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.
- The safety factor Ω and resistance factor Φ used to determine the ASD and LRFD strengths are based on AISI S100.
- The values for 16 ga., 18 ga., 20 ga. and 22 ga. are based on the calculations per AISI S100.
- 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 AISI S100.
- 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.
