Customer Reviews (4.2 / 5 · 5 reviews)

Jason X. ★★★★★

Driving these into dense oak beams for a deck frame was surprisingly easy with a pre-drilled pilot hole, and the 18/8 stainless heads show zero rust after a week of rain.

Jason T. ★★★★★

Finally got these installed for a deck repair, and the 18/8 stainless steel gives me peace of mind against rust in wet weather. The hex head bit into the wood cleanly with no stripping—definitely solid holding power for the heavy timber frame.

William ★★★★☆

Used these to tie a pergola into the house framing, and the stainless steel is a nice peace of mind against rust in wet weather. Would have liked a few more screws in the pack for the price, but the threads bit into the wood really cleanly with no stripping.
