براغي غطاء مقبس M10-1.25 × 40 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مؤكسد أسود حراري (100/عبوة)

The black oxide finish on these M10 screws held up perfectly when I used them to secure a jig on my drill press. The hex socket drive makes installation quick and they feel solid at exactly 40mm long.

The hex socket on these is deep and precise, so my hex key fits snug without any wobble. They threaded smoothly into my jig plate, and the black oxide finish looks clean and professional. For the price on a hundred pack of 12.9 alloy, this is a solid deal.

All 100 arrived in one sealed pack, and the black oxide finish looks uniform across every single one. Threads are clean and engagement in my jig plate was snug from the first bolt. These M10s are exactly what I needed for tooling.
