Eli G. ★★★★★

The unthreaded grip section made alignment in my fixture a breeze—no more fighting threads through the hole. All fifty arrived clean and properly coated, and the hex heads seated squarely with a standard wrench.

Miles ★★★★★

Zinc plating is holding up nicely after a week of outdoor use, no rust spots yet. The unthreaded grip section seated clean against the steel bracket, and all 50 heads came out of the box without any burrs or dings.

Carter R. ★★★★★

The partially threaded shank gave me exactly the grip length I needed for my trailer hitch mount. These bolts drove in smooth and the hex head grabbed my socket without any slipping.
