براغي رأس زر M8-1.25 × 65 مم | محرك سداسي | ملولبة جزئيًا | فئة 8.8 من سبائك الصلب بأكسيد أسود حراري (100 / عبوة)

The partially threaded design seated perfectly against the shoulder in my jig, and all 100 pieces came out of the bag with a consistent, even black oxide finish. Class 8.8 alloy steel feels plenty rigid for the tooling I'm building, no stripped sockets on the first ten I've torqued down.

Black oxide finish looks sharp and the hex socket drives clean without cam-out, so far. Threads seated smoothly into my fixture plates, and the 65mm length gave me just enough bite for a stacked setup.

I needed some longer fasteners for a jig I'm building and these 65mm socket caps threaded perfectly into existing M8 tapped holes. The hex drive made installation much smoother than using a hex key on standard bolts.
