Hazel X. ★★★★★

Picked up a pack for some tooling fixtures and the hex socket drive seated perfectly with a standard Allen wrench. The threads were clean and consistent across the entire 800-piece batch, which saved me a lot of rework time.

Grace W. ★★★★★

The black oxide finish on these screws gives them a clean, uniform look that holds up well on my machinery frames. The hex socket drive makes them easy to torque down without stripping, and the 2-1/2" length fits my precision assemblies perfectly.

Carter ★★★★★

Bought these for a jig I’m building and the black oxide finish gives them a nice, uniform grip that’s easy to handle with oily fingers. The hex socket drive seated perfectly with my Allen wrench, no stripping even at full torque. Solid packing for the count, too — every one of the 800 came out clean
