Customer Reviews (4.8 / 5 · 5 reviews)

Brian ★★★★★

The 316 stainless steel feels solid and premium, and the hex head made torquing them into pressure-treated oak effortless. They drove cleanly with zero stripping, exactly what I needed for a deck railing that faces coastal weather.

Madison ★★★★★

Put these to work on a timber frame project, and the 316 stainless held up through a week of rain without a single spot of rust. The hex head made driving them with a socket wrench a seamless operation.

William ★★★★★

I've been using these lag screws for a deck repair, and the 316 stainless steel is already holding up well against the coastal weather. They sank into the pressure-treated wood cleanly with a socket wrench, and the 75-pack gave me plenty for the whole project without any stripped heads.
