Customer Reviews (4.8 / 5 · 5 reviews)

Thomas J. ★★★★★

I used these to fasten some heavy crossbeams on a deck rebuild, and the coarse threads grabbed the treated lumber perfectly. The 316 stainless finish gives me peace of mind about rust in wet weather.

Carter E. ★★★★★

The hex heads bit into the pressure-treated timber cleanly with a ratchet, no stripping or wobble even at full torque. I grabbed the 125-pack so I’m set for the deck and the dock framing, and the 316 finish looks like it’ll shrug off the salt air for years.

George A. ★★★★★

I needed serious corrosion resistance for a dock project, and these 316 stainless lag screws fit the bill perfectly. The 5/8" diameter gives me confidence they won't strip out in treated lumber, and the threads bit into the wood smoothly with an impact gun.
