Customer Reviews (4.8 / 5 · 5 reviews)

Andrew D. ★★★★★

The square neck really locks them in tight so they don't spin while you're tightening them down. I used these for a heavy wooden gate and they held perfectly without stripping the material.

Madison ★★★★★

The zinc plating on these bolts looks clean and even, so they should hold up fine outdoors. The square neck seated perfectly into the wood when I tightened them with a wrench, and the 8-inch length was exactly what my swing set needed.

Sebastian ★★★★★

I needed 8-inch bolts for a deck repair and these were just the right length—the zinc coating looks clean and even, and the head sits flush.
