M5-0.8 × 30mm براغي ذات رأس أسطواني بمقبس سداسي | محرك سداسي | ملولبة جزئيًا | فئة 8.8 سبيكة فولاذ معالجة حرارياً بأكسيد أسود (400/عبوة)

The hex socket drive bites cleanly without any stripping, which mattered when I torqued them into my jig frame. Partially threaded design kept alignment solid for the precision assembly I needed, and the black oxide finish took a light oiling without fuss.

I was worried the black oxide finish would chip off during assembly, but not a single one of these M5 screws has flaked on me. They hold perfectly when building jigs, and the hex socket drive makes tightening them a breeze.

Got my order of 400 and they’ve been perfect for my jigs—the black oxide finish gives them a nice, grippy look and the hex drive fits snugly without stripping. I’ve used about fifty so far and not one has had a burr or issue.
