Customer Reviews (5.0 / 5 · 5 reviews)

Victoria E. ★★★★★

Installed these on a pergola project and the 6-inch length gave plenty of bite into the beams. The square neck seated perfectly into the wood, keeping the bolts from spinning while I tightened the nuts.

Samuel N. ★★★★★

The square neck on these bolts grabbed the wood perfectly, no spinning during installation. I used them to attach a heavy workbench leg, and the 6-inch length was just right for a solid connection. Plain steel is fine for indoor projects, and the full threading gave plenty of grip.

Olivia ★★★★★

The square neck under the head bites into the wood just as it should, so I didn't need a wrench to keep them from spinning while I drove them into the deck frame. All 20 bolts came with clean threads and a consistent zinc-free plain finish, and they seated flush without any burrs.
