براغي رأس كبس HOlO-KROME 87112 M6-1 X 40 مم | رأس مسطح محرك سداسي | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

Installing these into a jig fixture was smooth—the hex socket seated perfectly without any stripping. The 40mm length was exactly what I needed for that application, and the pack of 100 means I’ve got plenty of spares for future projects.

The black oxide finish on these M6 bolts looks really clean against my machine frame, and the hex socket drive makes tightening in tight spots much easier than a standard hex head. I used a dozen for a precision assembly and they all threaded smoothly without any binding.
