براغي رأس كبس M8-1.25 × 130 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مع أسود حراري أكسيدي (100 / عبوة)

The black oxide finish on these actually looks and feels quality, not just cosmetic. The partial threading gave me the exact grip I needed for a jig build, and the hex socket drove in clean without any stripping.

Used these for a heavy-duty precision assembly on my milling machine and the black oxide finish still looks great after torquing them down. The hex socket drive seated perfectly with my Allen key, no stripping at all.

I'm building a jig and the 130mm length on these is perfect for reaching through two layers of steel plate. The hex socket drives cleanly without stripping, even when torquing to spec. They feel solid in hand.
