Victoria ★★★★★

Grabbed a pack of these for mounting some aluminum brackets, and the shoulder design gave me a much cleaner, more secure fit than standard screws. Threaded smoothly into the 1/4-20 holes without any binding, and the knurled heads make hand-tightening a breeze. Will definitely be coming back for more

Sebastian G. ★★★★★

The zinc plating on these thumb screws feels smooth and should prevent rust well. They work perfectly for tightening down my jig fixtures.

Jacob Y. ★★★★★

The knurled edges give you a solid grip even with greasy fingers, and the zinc coating looks clean out of the bag. I've used about forty of them on a shelving frame and every one threaded smoothly without a single stripped head.
