براغي غطاء مقبس HOLO-KROME 69414 M6-1 × 20 مم | محرك سداسي منخفض الرأس | سبيكة فولاذية أكسيد أسود حراري (100 / عبوة)

The low head profile cleared the tight clearance I have on this fixture without any issue, and the black oxide finish looks and feels properly done. Threads ran smooth into all 100 holes, no binding or gunk in the pack.

The black oxide finish on these screws is really nice and uniform—they seated perfectly in my drill jig without any binding. For under twenty bucks for a hundred, you’re getting solid quality for tooling work.

Installed these in a jig I’m building and the low head profile cleared a tight spot perfectly. The hex drive seated securely without any stripping, even at higher torque.
