Product Details

Strong-Drive® XL LARGE-HEAD METAL Screw

Product Details

Strong-Drive structural fasteners are engineered and extensively tested to meet the needs of the most demanding wood-to-metal applications. 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 (compatible driver bit — BITHEXR516-R1)
#5 drill point
Quik Guard® coating for corrosion protection
5/8" diameter integral washer

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

P_ss and P_ts 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 F_y = 33 ksi

Values are based on steel members with a minimum yield strength of F_y = 33 ksi and tensile strength of F_u = 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.
