Customer Reviews (4.4 / 5 · 5 reviews)

Leo ★★★★★

Had to replace the deck railing on an old porch and these bolts grabbed perfectly — the square neck really does lock in tight and stop spinning. Nice zinc finish too, no rust so far after a week of rain.

Eva J. ★★★★★

I've been using these 3/8-16 carriage bolts for a heavy-duty deck repair, and the zinc plating is holding up better than expected against the damp weather. The square neck design really does lock into the wood, just like it says.

Nicholas ★★★★★

The square neck under the smooth head grabbed the wood right away and didn't spin a single turn while I tightened them. These 8-1/2-inch bolts are solid, and the zinc coating looks even and clean out of the package. Perfect for my deck frame — exactly what I needed and then some.
