براغي HOLO-KROME 86085 M12-1.75 X 50mm ذات رأس أسطواني | رأس زرية محرك سداسي | فولاذ سبائكي مؤكسد حراري أسود (50 / عبوة)

Bought these for a fixture plate and the black oxide finish is even and uniform across all fifty, no rough edges on the threads. The M12s seated cleanly into tapped holes without any binding, which is exactly what I needed for repeat assembly work.

Threaded all fifty of them into a jig plate this morning and every single one seated perfectly without a single cross-thread. The black oxide finish is even and consistent, which matters when you're building tooling that needs to look as good as it works.

The black oxide finish on these M12 screws is holding up perfectly against oil and metal chips in my jig setup. They seated cleanly with a hex driver and the 50mm length gave just the right thread engagement for my fixture plate.
