HOLO-KROME 87174 براغي رأس مقبس M10-1.5 × 80 مم | محرك رأس سداسي مسطح | فولاذ سبيكة أكسيد أسود حراري (50 / عبوة)

Threads were perfectly clean, no burrs or rough edges, and every one of the 50 seated flush in my jig plate without a single fight. The black oxide finish already matches the rest of my tooling, so they'll blend right in on the shop floor.

Installed these on a jig I’ve been building, and the flat head hex socket fits perfectly with my driver. The 80mm length gave just the right reach for the assembly, and the black oxide coating hasn’t shown any wear after a few tight turns.

The black oxide finish looks good, but the threads on a few of the screws had a slight burr that needed cleaning before installation. They fit well in the jig I was making once prepped.
