HOLO-KROME 76230 M8-1.25×15mm براغي ذات رأس أسطواني بمقبس سداسي | سبيكة فولاذ أكسيد أسود حراري (100/عبوة)

Putting together a new fixture for the mill, and these black oxide screws slid right in without any binding. The hex drive seated perfectly, and the 15mm length was exactly what I needed for that tight tolerance.

The black oxide finish on these M8s is flawless and they drive in smooth without any binding. I used a full pack on a jig build and every single one seated perfectly with a hex key.

Pulled these out for a tooling fixture at work, and the black oxide finish is holding up better than I expected against minor scuffs. The hex socket drive seated perfectly with my torque wrench on the first try.
