براغي رأس أسطوانية M8-1 × 16 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي من الفئة 12.9 مع أكسيد أسود حراري (200 / عبوة)

The black oxide finish on these M8 socket cap screws looks clean and holds up well in my jig setup. The hex socket drive made installation straightforward, and the 12.9 alloy steel feels solid. A solid choice for precision work without breaking the bank.

Used these on a precision assembly fixture and the hex socket drive made installation quick with a standard Allen key. The black oxide finish seems durable and doesn't chip during tightening. Exactly what I needed for tooling.

These are holding up perfectly on a jig I built last week. The hex socket drive makes them easy to torque down, and the black oxide finish looks clean and professional.
