براغي رأس كبس 3/8-16 × 2-1/4 بوصة | محرك سداسي منخفض الرأس | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

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.

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.

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.
