Customer Reviews (4.4 / 5 · 5 reviews)

Timothy ★★★★★

The square neck grabbed the wood perfectly on my deck rebuild, no spinning at all. Each bolt threaded smoothly into the nuts without any binding.

Julian ★★★★★

Used these to build a heavy-duty workbench and the 6-1/2" length gave plenty of bite through two layers of 2x6 lumber. The smooth dome head looks clean and the square neck locked in place without any spinning.

Steven ★★★★★

I was pleasantly surprised by how clean the threads were on every single bolt in the package. These are holding up my heavy deck railing perfectly, and the 6-1/2 inch length was exactly what I needed for this project.
