Customer Reviews (4.2 / 5 · 5 reviews)

Scarlett ★★★★★

The hex heads fit my 18mm socket perfectly, making installation on my milling machine straightforward. These fully threaded 316 stainless screws are much sturdier than the zinc-plated ones I had before.

Isabella Q. ★★★★☆

Used these to replace some rusted bolts on a saltwater dock railing, and the 316 stainless held up perfectly so far. The hex head made it easy to drive with a socket, and the full threading gripped the wood securely. Only gripe is the pack size is a bit small for larger projects.

Richard V. ★★★★☆

The threads are clean and consistent, so they started by hand without any binding. I'd have liked a slightly tighter fit on the hex head for the socket, but they held torque fine during assembly. Solid choice for marine-grade fastening needs.
