Customer Reviews (4.8 / 5 · 5 reviews)

Avery K. ★★★★★

Used a few in a custom fixture build and the flat head seated perfectly flush, no issues stripping with the hex drive. The black oxide coating held up well during tightening—solid feel throughout.

Eva ★★★★★

The hex socket drive made installation really easy with my allen wrench, and the flat head sits flush against the jig surface perfectly. I’ve already used half the pack for a precision assembly project, and they held tight without any stripping.

Sebastian E. ★★★★★

The black oxide finish on these screws is flawless, no chipping or uneven spots right out of the package. I used the full box on a jig build and every thread engaged smoothly with zero binding. Solid purchase for precision work.
