HOLO-KROME 76244 براغي ذات رأس أسطواني M8-1.25 X 30mm | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراري (100 / عبوة)

Installed these on a jig I’m building and the black oxide finish made alignment dead simple. The hex drive seated perfectly without any cam-out, and at 30mm they’re exactly the right length for my fixture.

Ran out of these faster than I thought after a weekend of building custom tooling—the black oxide coating held up nicely against steel chips without any galling. Threads started clean on every single screw in the pack, which saved me a ton of re-tapping time.

The black oxide finish on these M8s is exactly what I needed for a fixture assembly—no rust worries in the shop. The hex socket drive seated cleanly with my driver, and all 100 heads were uniform right out of the pack.
