Description & Documents
The WS35-BP Wood Screws 1/4" X 3-1/2" (900/Box) are self-drilling screws used for numerous framing applications. Screws feature a reverse locking serration on the bottom of the screw head to help prevent over tightening against a steel plate. The USP head stmap identifies screws for easy inspection. Zinc finish.
- Install using a low speed clutch drill with 3/8" hex head driver. The washer head should be flat to the surface and the serrations will oppose turning and release the cutch. Do not over-tighten the screws.
- Not For Use With Treated Lumber
- Installing the screw at an angle may introduce additional bending and tension forces into the fastener if the screw head is not flat on the bearing surface. Care should be given to ensure the fastener is installed perpendicular to the plane of the side plate.
