Lucy Z. ★★★★★

These 316 stainless lag screws went through the treated timber on my dock project without any binding. The hex heads hold a socket perfectly, and the 5-inch length gave me the bite I needed into the joists. For marine-grade hardware, this pack was a solid deal.

Grace ★★★★★

The threads cut cleanly into the pressure-treated timber without any stripping, and the 316 stainless finish already looks like it will outlast the wood. These are hefty screws that give you real confidence when bolting together a heavy-duty frame.

Mia ★★★★★

I needed these for a dock project where salt spray eats regular screws in a season. The 5/8" x 5" length grabbed deep into the timbers, and the 316 stainless hex head gave a solid bite without rounding. They drove in straight and felt really heavy duty for the price.
