Simpson Star Drive

Build to Withstand the Elements. Choose Type 316 stainless steel for seaside and coastal environments. The stainless-steel Bugle-Head Wood screw provides superior corrosion resistance while fastening all types of wood decking, including cedar, redwood and preservative-treated woods (non-hardwood). The 6-lobe drive recess provides for a secure bit which reduces cam-outs and leads to longer bit life. The bugle-head feature engineered for flush countersinking yields beautiful fastening results for a more concealed, professional finish.

Choose your style. 305 or 316 Stainless.

Choose your package size. Available in 1 lb, 5 lb, and Bucket quantities.

Best-in-class, load-tested fasteners: Strong-Drive structural fasteners are engineered and extensively tested to efficiently meet your most demanding wood and metal applications. Stronger can also be faster. The Strong Drive family is designed to install easier than other fastening methods, which saves time and money.
Many of our structural screws have been redesigned with our patented SawTooth point to provide faster starts and easier driving — the difference will amaze you!
