Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn ★★★★★

The square neck grabbed tight into the wood on my gate rebuild, and the zinc plating looks clean enough to resist some weather. It took a while to find these 11-inch lengths, but they’re solid for heavy framing.

Abigail ★★★★★

I needed long bolts for a deck repair, and these 11-inch carriage bolts were exactly the right length. The zinc plating is smooth and even, and the square neck seated perfectly in the pre-drilled hole without any slipping.

Violet ★★★★★

The square neck grabbed the wood instantly when I tightened the first one, so no spinning or cursing like with some other bolts. The 11-inch length is exactly right for my beam connection, and the zinc coating looks clean and even across all twenty-five pieces.
