Customer Reviews (4.8 / 5 · 5 reviews)

Claire F. ★★★★★

The hex heads on these lag screws fit my socket perfectly, making installation much easier than I expected. For a marine-grade fastener, the price per piece is surprisingly reasonable for a full box of 500.

Isabella C. ★★★★★

Just drove the last one into a timber frame for a covered porch—all 500 of them went in without a single stripped head. The 316 stainless is already paying off; I left a few out in the rain and no rust after two weeks. Holding power feels rock solid at this length.

John R. ★★★★★

I was worried these would be too short for my timber bench, but the 4-1/2" length grabbed perfectly into the joists. The 316 stainless finish feels solid and rust-proof, which is exactly what I needed for an outdoor project.
