The Simpson Strong-Tie Bugle-Head Deck Screw Square Drive is designed for fastening all types of wood decking, including cedar, redwood, and preservative-treated lumber. Made from 305 stainless steel for superior corrosion resistance, these screws deliver long-lasting performance in exterior environments.

For professional results, the bugle head ensures flush countersinking, leaving a clean finish while pulling boards tightly to framing. The square-drive recess provides secure engagement and reduces cam-out, while a sharp Type 17 point delivers fast starts. Each 350-count pack covers approximately 100 sq. ft. of decking, making these screws both efficient and reliable for deck building.
