براغي رأس كبس مقبس M12-1.75 × 80 مم | محرك مقبس سداسي منخفض الرأس | خيط جزئي | فولاذ سبائكي من الفئة 10.9 مع أكسيد أسود حراري (25 / عبوة)

The partially threaded design made installation on my press fixture much easier than fully threaded bolts would have been. The black oxide finish seems durable and the hex socket drive gave a solid grip without stripping.

I’ve been using these for some custom jigs and tooling fixtures, and the partially threaded design really helps with alignment under load. The hex socket drive feels solid, no stripped heads even after torquing them down hard. Pack of 25 is nice for the price, too.

The black oxide finish gives these a nice, even look and they threaded into my jig without any binding. Partial threads are exactly the right length for the clamping depth I needed, and the hex socket seated the driver firmly with zero stripping.
