براغي رأس أسطوانية M8-1.25 × 50 مم | رأس منخفض محرك سداسي | ملولبة جزئيًا | فئة 10.9 من سبائك الصلب مع أكسيد أسود حراري (100 / عبوة)

The hex socket grabbed my driver bit cleanly on every single one of the hundred, which is rare for a bulk pack. The black oxide finish also looks sharp against the aluminum frame I mounted them on. Definitely ordering another box for the next project.

I needed a low-head screw for a tight clearance on my milling fixture and these M8s fit perfectly. The black oxide finish looks clean and the hex socket drive gripped securely without stripping.

The partially threaded shaft made them perfect for jig work where I needed a clean, flush fit. The black oxide finish is even and tough, no flaking after tightening. These will be my go-to for future tooling builds.
