Natalie U. ★★★★★

I’ve used a lot of lag screws for timber framing, and these 316 stainless ones are the first I haven’t had to worry about rust spotting after a wet season. The 5-1/2 inch length gives a seriously solid bite into the wood, and all 200 came with clean threads and sharp points. They’re not the cheapest

Grace N. ★★★★★

Installed these on a dock that takes a beating from saltwater, and the 316 stainless steel is holding up perfectly with zero rust after months. The hex head made driving them in with a socket driver much easier than I expected.

Elizabeth C. ★★★★★

Put these into a deck frame rebuild and the 316 stainless really gives peace of mind against rust. They bit cleanly into the pressure-treated wood without needing much pre-drilling.
