Customer Reviews (4.6 / 5 · 5 reviews)

Isabella ★★★★★

The black oxide finish on these screws held up perfectly during assembly, no galling or wear. The low head profile was exactly what I needed to clear a tight guard on my jig fixture.

Scarlett Y. ★★★★★

Installing these low head screws in a tight jig assembly was way easier than I expected thanks to the hex socket drive. The black oxide finish looks sharp and they held up perfectly during a test run.

Mia ★★★★★

The black oxide finish on these screws gives them a nice, uniform look and seems like it will resist rust well in my shop. I used them to secure a fixture plate on my milling machine, and the low head profile was perfect for tight clearance.
