Customer Reviews (4.8 / 5 · 5 reviews)

Carter W. ★★★★★

The partially threaded length on these is exactly right for clamping thick brackets without bottoming out, and the hex heads grabbed my socket wrench with zero rounding. Sixty bucks for a 30-pack of genuine A307 bolts feels like a solid deal.

Olivia M. ★★★★★

These threaded cleanly into my steel frame jig without any binding, and the partial thread gave just the right grip for a heavy load. The zinc-free plain finish is exactly what I needed for a project that couldn't risk corrosion from a coating.

Aurora ★★★★★

I needed some heavy-duty bolts for a piece of farm equipment, and these heavy hex heads have plenty of grip thanks to the 4-1/2-inch length. The plain finish is exactly what I was after for a clean, no-nonsense installation.
