Customer Reviews (4.8 / 5 · 5 reviews)

Emily ★★★★★

Installing these into a heavy timber frame was a breeze, and the threads bit cleanly without stripping. The 316 stainless feels solid and should hold up well in our damp climate.

Ella ★★★★★

The hex head grabbed my socket wrench perfectly and sank into the pressure-treated beams without a hint of stripping. I’ve had lesser screws corrode on saltwater docks, but these 316 stainless ones should outlast the wood itself.

Charlotte D. ★★★★★

Most of my deck ledger was starting to corrode near the coast, but these 316 stainless lags show zero rust spots after three months of rain and salt air. The 5-1/2 inch length gave my 4x4 posts a solid bite into the beams, and the hex heads made seating them with a socket wrench effortless.
