HOLO-KROME 87202 براغي رأس أسطوانية M12-1.75 × 90 مم | رأس مسطح محرك سداسي | فولاذ سبائكي أكسيد أسود حراري (50/عبوة)

Installed these on a jig I’ve been building for custom tooling, and the 90mm length gave me just the right thread engagement without needing a spacer. The hex socket drive seated cleanly with my driver, and the black oxide coating seems to resist oil well.

The black oxide finish grabbed onto my hex wrench without slipping, which made installing these into a jig frame much smoother than I expected. They seated flush and the 90mm length was perfect for the through-hole I needed.

Needed a batch of solid cap screws for a jig rebuild, and the black oxide finish on these M12s gave them a clean, uniform look straight out of the package. Threads ran smoothly into our tapped holes without any binding.
