براغي رأس مقبس M5-0.8 × 12 مم | رأس زر محرك سداسي المقبس | ملولبة بالكامل | سبيكة فولاذ فئة 12.9 مؤكسدة حرارياً سوداء (600 / عبوة)

The hex socket drive sits perfectly flush on my tooling jigs, and the 12.9 alloy steel threading held up through a full day of heavy clamping without a single strip. Pack of 600 means I'll be set for a long time, and the black oxide finish looks sharp on my bench.

The black oxide finish on these M5 screws feels really durable, and the hex socket drive made installation a breeze with my metric allen keys. I've used about half the pack for jig setups so far without any stripping or burrs.

Finally, a batch of M5 screws where the hex socket actually fits the wrench snugly with no slop. The black oxide finish looks professional on my jig, and the 12.9 alloy steel feels reassuringly hard.
