Customer Reviews (4.8 / 5 · 5 reviews)

William ★★★★★

The square neck grabbed the wood immediately when I tightened these, so no spinning or cursing under the deck frame. Zinc coating looks even and clean, and all 200 arrived without a single bent or stripped thread in the box.

Benjamin ★★★★★

I needed exactly 200 for a deck project, and these zinc-plated bolts matched the carriage style I was after. The threads were clean and seated smoothly into the pre-drilled holes without any binding.

Aurora T. ★★★★★

The square neck on these bolts grabbed perfectly in the wood, no spinning at all while I tightened them. For the price, getting 200 zinc-plated fasteners that won't rust quickly is a solid deal.
