WS Hex Head Interior Structural Wood Screws
The WS Wood Screw is a self-drilling screw used for numerous interior
framing applications. For use in wood-to-wood and steel-to-wood
applications. Head stamped to indicate length for easy inspection.
Features and Benets:
• 1/4" diameter
• No predrilling
• Type 17 point reduces installation torque and splitting
• 3/8" Hex Drive
• Length identication stamps on all WS heads
Materials: 1/4" diameter Grade 5 steel
Finish: Yellow Zinc
Codes: IBC, FL, LA
Installation:
• Screws are self-drilling.
• Install using a low speed clutch drill with 3/8" hex head driver. The
washer head should be at to the surface and the serrations will
oppose turning and release the clutch. Do not over-tighten the screws.
• Care should be given to ensure the fastener is installed perpendicular
to the plane of the side plate.

1) Zinc = Yellow Zinc Dichromate.
2) Allowable shear loads assume a side plate tensile strength of 45 ksi for 14 gauge and 10 gauge, 52 ksi for 7 gauge and 58 ksi for 3 gauge.
3) Shear loads for wood-to-wood connections assume a side member thickness of 1-1/2".
4) Loads are for 100% duration of load factors, and may be increased for other duration factors in accordance with the NDS.
5) Withdrawal loads for steel-to-wood connections assume a side plate thickness of 1/4" or less.
