براغي رأس أسطوانية M10-1.5 × 35 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 8.8 بأكسيد أسود حراري (100/عبوة)

The black oxide finish on these M10 bolts resists marring better than I expected when I was torquing them into a steel jig. The threads cut cleanly and the 35mm length was spot-on for what I needed. These are going back into my parts drawer for the next project.

The hex socket drive on these M10-1.5 screws gave me a solid grip when assembling a precision fixture, and the black oxide coating looks clean. They threaded smoothly into tapped holes without any binding. Exactly what my tooling setup needed.

The threads on these are perfectly clean, no burrs or rough spots, and the black oxide finish looks sharp on my jig. They drove in smooth with a hex key and held tight in steel. Just what I needed for tooling.
