براغي مقبس M24-3 × 110 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 8.8 أكسيد أسود حراري (10 / عبوة)

The partially threaded design made alignment much easier when securing the base plate on our milling machine. These bolts tightened down smoothly with a hex key, and the black oxide finish looks proper for industrial use.

Installed these in a jig for holding automotive parts, and the 8.8 grade alloy steel held torque perfectly without any stripping. The partially threaded design gave just the right grip depth for my 110mm thick plates.

The black oxide finish wiped clean easily and the hex socket drove true without any wrench slip, even under decent torque. Sized the threads against a jig plate and they seated perfectly, just the right engagement length at 110mm. Exactly what I needed for a precision assembly.
