Customer Reviews (4.4 / 5 · 5 reviews)

Hannah W. ★★★★★

I needed these for a deck repair, and the 11-1/2-inch length was exactly what was required. The zinc plating looks clean and should hold up well against weather.

Ella G. ★★★★★

The square neck on these carriage bolts gripped the wood perfectly during assembly, no spinning at all. At 11-1/2 inches long, they were just what I needed for my heavy timber project. The zinc plating looks clean and consistent across all 120 pieces.

William ★★★★☆

The 120-pack is perfect for larger projects, and the zinc plating looks clean and seems durable. I used them for a timber frame repair on my deck, and they held fast without any slipping. Only wish the threads were a bit longer for thicker applications.
