براغي رأس مقبس HOLO-KROME 69422 M6-1 × 30mm | رأس منخفض بمقبس سداسي | سبيكة فولاذية أكسيد أسود حراري (100/عبوة)

These are going into all my jigs and fixtures now. The black oxide finish gives them a nice grip in the wrench and they thread in cleanly without any binding, even after a few assembly cycles.

The M6-1 x 30mm length is exactly what I needed for my jig setup, and the black oxide finish hasn't shown a single scratch after repeated use. They thread in smoothly with no binding, and the low head lets me fit them into tight spots that standard screws would never clear.

The low head profile on these is a lifesaver for tight clearance spots on my precision assembly rig. Threads cut cleanly into the tapped holes without any binding, and the black oxide finish has held up well against light shop grime.
