Customer Reviews (4.4 / 5 · 5 reviews)

Adam I. ★★★★★

The square neck grabbed the wood instantly, no spinning or cussing even in tight spots. Zinc plating looks clean and the threads were all consistent across the hundred. Solid value for a full box.

Sebastian I. ★★★★★

I used these carriage bolts to build a simple outdoor bench, and the square neck underneath each head really did lock into the wood without spinning. The rounded heads give it a clean look, and the zinc plating seems like it will hold up fine.

Jason T. ★★★★★

The zinc plating on these bolts looks clean and should resist rust well. Fully threaded gives you flexibility, and the square neck locked into the wood without slipping. Exactly what I needed for building a sturdy bench.
