Customer Reviews (4.8 / 5 · 5 reviews)

Grace C. ★★★★★

Fit perfectly on a small jig I'm building—the partially threaded shank gave just the right grip length. The threads ran smoothly into pre-tapped holes without any binding.

Benjamin K. ★★★★★

The zinc coating looks solid and should resist rust well in my garage projects. These bolts fit perfectly into my steel brackets, and the unthreaded grip section made alignment a breeze.

Adam ★★★★★

The partially threaded shank made aligning these bolts into my steel frame a breeze, and the zinc plating seems solid enough to resist rust in my garage. A full 100 count for under twenty bucks is a steal for any decent-sized project.
