5/16 In. X 4 In. L Star Climatek W-cut Structural Wood Screws 25 Pk

GRK RSS structural wood screws deliver strong, reliable connections for framing, decking, fencing, and heavy-duty construction projects. These fasteners are engineered to simplify installation while providing the clamping force and holding power that professional builders and serious DIYers demand. The star drive design and proprietary Zip-Tip feature allow you to drive these screws quickly into most wood types without pre-drilling, reducing installation time and labor on job sites.

The washer head provides superior clamping force for strong joints. The W-Cut thread design is specially engineered to enhance penetration into wood. A Climatek coating adds durability for long-term outdoor use, with a black finish that not only looks great but also shields the fastener from moisture.
