Robert Y. ★★★★★

Needed a full box of these for a batch of tooling fixtures and the black oxide finish looks properly done, no gummy spots or uneven coating. The threads chased clean through every hole I tapped, and the hex sockets engaged perfectly without any stripped corners.

Brian R. ★★★★★

Installed these in a jig for a production run and the hex socket took torque without any stripping. The 50-count package is exactly what I needed for this project.

Violet K. ★★★★★

The black oxide finish on these screws is really clean and uniform, making them look great on my precision tooling setup. They threaded smoothly into tapped holes without any binding. Definitely a solid buy for the price.
