براغي رأس مقبس M5-0.8 X 35mm | رأس مسطح محرك مقبس سداسي | جزئي الخيط | فئة 12.9 فولاذ سبائكي مؤكسد أسود حراري (400 / عبوة)

The black oxide finish on these screws is holding up well in my tooling fixtures, and the hex socket drive makes installation a breeze. I’ve been using them for precision assemblies, and the 35mm length is spot on for what I needed.

Bought these for a batch of custom jigs and the black oxide finish holds up well under repeated clamping pressure. The flat heads sit flush perfectly in my counterbores, and having 400 in the pack means I won't run out before the next project.

The threading on these is clean and consistent across the whole box of 400, which made them easy to seat in a jig I’m building. The black oxide finish gives them a nice, uniform grip and they’ve held up well under repeated tightening without stripping the socket.
