براغي رأس مقبس 5/8-11 × 1-1/2" | محرك مقبس سداسي منخفض الرأس | فولاذ سبائكي أكسيد أسود حراري (50 / عبوة)

The black oxide finish on these screws is really uniform and clean, which made them look great on my tooling project. They threaded smoothly into my jig without any binding, and the low head profile gave me the clearance I needed.

Used these for building a custom jig and the black oxide coating really resists wear on the threads even after repeated tightening. The low head profile was perfect for tight clearance spots on my assembly.

The hex socket drive seats perfectly on my Allen wrench with zero wobble, and the low head profile cleared the tight clearance on my jig fixture without any grinding. The thermal black oxide coating has a uniform, non-glare look that's held up well through a week of shop use.
