M10-1.5 × 30mm براغي غطاء بمقبس | محرك مقبس سداسي | ملولب بالكامل | فولاذ سبائك كلاس 12.9 أكسيد أسود حراري (200/عبوة)

I've been using these M10-1.5 socket cap screws in a jig I built, and the black oxide finish has held up great without any rust through a solid week of assembly work. The hex socket drive bites securely with a standard Allen key, making installation quick and precise.

Threaded all the way to the head, so they grip tight even in shallow holes—perfect for my jig build. The black oxide coating seems durable and hasn't chipped during installation.

The thermal black oxide finish is holding up great on my tooling fixtures, no rust after a month of oily shop use. The hex socket drive seats perfectly with a standard Allen key, and all 200 came with clean threads and consistent length. For the price per piece, these are a solid buy for anyone buil
