Customer Reviews (4.4 / 5 · 5 reviews)

Samuel I. ★★★★★

Put these on a heavy timber gate and the fully threaded length grabbed deep into the wood, holding solid. The zinc coating looks clean and should keep rust away for years. Exactly what I needed for a rugged outdoor build.

Olivia ★★★★★

Put these to work on a heavy-duty swing set frame in my backyard, and the square neck held tight against the lumber without any spinning. The 6-inch length gave plenty of bite for a solid connection, and the zinc coating seems like it will resist rust well.

Harper ★★★★★

These bolts were exactly what I needed for my deck project; the square neck under the head locked into the wood perfectly and kept them from spinning while I tightened the nuts. The zinc plating looks clean and should hold up fine outdoors.
