Penelope U. ★★★★★

Needed these for a heavy-duty jig build and the partially threaded design let me get just the right clamping force without bottoming out. The black oxide finish feels tough and hasn’t shown any wear after tightening a few of them to spec.

Jacob R. ★★★★★

The hex socket drive made installation effortless, and the partially threaded design held my assembly tightly without slipping. Definitely solid hardware for the price.

Henry ★★★★★

I needed a heavy-duty fastener for a jig I’m building, and these 10" long partially threaded screws fit the bill perfectly—the hex socket drive made installation smooth even in tight spots.
