Henry G. ★★★★★

These 316 stainless lag screws were used to fasten my dock stringers. The threads cut clean without stripping, and the hex head let me really torque them down with a socket. Should hold up great in the saltwater.

Joshua Z. ★★★★★

Installed these in a cedar timber frame for a deck project, and the 5/8" diameter gave me real confidence in the connection. The 316 stainless threads cut cleanly into the wood without needing a pilot hole wider than recommended.

Sophia W. ★★★★★

The hex head on these 316 stainless lag screws really bites into the wood without stripping, and the corrosion resistance gives me peace of mind for outdoor use. They drove in smoothly with a socket wrench and hold tight in my deck frame.
