براغي مقبس M24-3 X 160mm | محرك سداسي | خيط جزئي | فولاذ سبائكي فئة 8.8 أسود حراري (10 / العبوة)

The hex socket drive grabbed the Allen key cleanly with zero rounding, and the black oxide finish looks properly industrial on my jig. Threaded portion measured exactly where I needed it for a 60mm grip. These are solid for the money.

These M24-3 socket cap screws fit perfectly into my jig, and the partially threaded design really helped hold everything together. The hex socket drive makes them much easier to tighten than standard bolts. A solid choice for tooling work.

The black oxide finish on these screws is really durable and resists scratches well during assembly. Used them to secure a heavy-duty press fixture and the Class 8.8 alloy steel handled the torque without any flex.
