براغي ذات رأس مقبس M5-0.8 × 12 مم | محرك سداسي مسطح الرأس | ملولبة بالكامل | فولاذ سبائكي من الفئة 10.9 معالجة بأكسيد أسود حراري (1200 / عبوة)

The hex socket drive on these M5 screws grips perfectly without stripping, even when I’m putting together a tight jig setup. They’re all exactly 12mm long with clean threads, and the black oxide finish looks solid.

I was pleasantly surprised by the uniformity of the black oxide finish across all 1,200 screws for my recent jig build. They drive cleanly with a hex key and hold torque well without stripping, perfect for precision work.

Installed these on a custom tooling fixture and the flat head seats perfectly flush, no wobble. The black oxide coating seems durable enough for repeated wrenching, and the 1,200 count means I won’t run out mid-project.
