Customer Reviews (4.4 / 5 · 5 reviews)

Sofia Y. ★★★★★

I needed to fasten some heavy crossbeams to support a deck extension, and these stainless steel lag screws drove in cleanly with no stripping. The 5/8-inch thickness gives me total confidence in the holding power for the load.

Henry ★★★★★

Used these to attach a heavy ledger board to the deck frame, and the 18/8 stainless steel gave me real peace of mind against rust. The threads bit cleanly into the pressure-treated wood without any stripping.

Adam ★★★★☆

The threads cut cleanly into the joists I was bolting together, and the stainless steel finish gives me peace of mind outdoors. Just wish the package included a few extra, since I needed more than 15 for my project.
