براغي رأس كبس M5-0.8 × 12 مم | مقبس سداسي | ملولبة بالكامل | سبيكة فولاذ درجة 8.8 مؤكسد أسود حراريًا (600 / عبوة)

The black oxide finish on these M5 screws looks sharp and uniform, and the hex socket drive engages perfectly every time—no stripped heads or slipping. I just finished a jig build and used about half the box, every single one threaded cleanly.

I was pleasantly surprised by how precisely these M5 screws threaded into my jig—no binding or wobble at all. The 12mm length was exactly what I needed for my tooling setup, and the black oxide finish looks clean and professional.

Needed a batch of these for some tooling fixtures, and the black oxide finish looks clean and consistent across all 600 pieces. The hex socket drive grips well without stripping, which is exactly what I needed for repeated assembly and disassembly in my precision setup.
