براغي رأس مقبس M5-0.8×8 مم | رأس زر محرك مقبس سداسي | خيوط كاملة | فولاذ سبائكي فئة 12.9 مؤكسد أسود حراريًا (600/عبوة)

The black oxide finish on these looks even better in person and feels properly tough, not just cosmetic. I’ve been using them in a test jig for two weeks now and not a single head has rounded out with the hex driver. For the price per piece, you can’t beat the consistency of the threading.

I needed a solid batch of M5 screws for a jig I'm building, and these 12.9 alloy steel ones fit perfectly without stripping. The hex socket drive makes them easy to torque down accurately, and the 600-count pack should last me a while.

The black oxide finish on these M5 screws gives them a nice, uniform look and seems to resist scratches well. I used a full bag on a jig fixture and every single one threaded cleanly with no stripping or binding. Exactly the precision fit I was hoping for.
