براغي HOLO-KROME 76240 M8-1.25 X 25mm رأس مقبس | محرك مقبس سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

Installed these in a jig I’m building and they threaded in smoothly with no binding. The hex socket drive grips the Allen key perfectly, even with moderate torque. Exactly what I needed for precision assemblies.

The black oxide finish on these screws looks sharp and held up well during assembly, no chips or uneven coating. The hex drive seated perfectly every time, which made running them into my jig frames a quick, frustration-free job.

I used these for a custom tooling fixture and the black oxide coating really holds up against oils from the shop floor. The hexagonal socket drive takes a standard bit without any wobble.
