Benjamin A. ★★★★★

Used these to bolt down a heavy press in my workshop, and the partially threaded shaft gave plenty of grip without bottoming out. The zinc coating looks uniform and should resist rust well in my garage environment.

Sophia L. ★★★★★

These things are beefy as hell, the 1-1/4" diameter is no joke. I used them to bolt down a heavy equipment base and the partially threaded shank gave plenty of grip without needing a ton of washers.

Christopher L. ★★★★★

These 1-1/4-7 x 7" heavy hex cap screws are solid, the zinc plating looks consistent and should resist rust well in my shop. The A307 grade B steel feels tougher than the generic hardware store bolts I usually grab. Perfect for securing some heavy machinery parts I've been working on.
