Edward Z. ★★★★★

Finally a 316 stainless bolt that doesn't strip when torqued to spec – the threading is clean and consistent all the way down. Used these for a marine railing repair, and the extra length gave just enough bite in the aluminum base.

Matthew H. ★★★★★

Used these for a boat railing repair and the 316 stainless held up perfectly in saltwater spray. The hex head gave a solid grip with my socket wrench, threads were clean all the way through. Just what I needed for a tough outdoor job.

Scarlett F. ★★★★★

I needed fully threaded bolts for a machinery rebuild and these M20s fit perfectly with zero slop in the threads. The hex head makes it easy to drive them with a socket.
