Customer Reviews (4.2 / 5 · 5 reviews)

Violet ★★★★★

Used a dozen of these on a jig I was building and the low head profile gave me just the clearance I needed. The hex drive seated perfectly without stripping.

Benjamin Y. ★★★★★

Used a full pack of these on a jig build and every single one seated cleanly without a single stripped thread. The low head profile cleared the tight clearance I had under the fixture plate, which was a relief.

Ruby H. ★★★★☆

The low head profile on these screws let me fit them into a tight spot on a tooling fixture where standard cap screws wouldn’t clear. They threaded smoothly and the black oxide finish looks clean. Only minor gripe is the package didn’t include any extras, so I’m ordering another pack for future proj
