براغي رأس مقبس M16-2 X 110mm | محرك سداسي المقبس | ملولبة جزئيًا | فئة 8.8 فولاد سبائك مطلي بالزنك (25 / عبوة)

Installed these on a custom tooling fixture and the partially threaded design made alignment much easier than fully threaded bolts. The black oxide finish on the alloy steel feels solid and hasn't shown any rust after a few weeks in a damp shop.

Grabbed a pack for a jig I was building and the zinc plating looks uniform with no flaking around the threads. The hex socket drive seated cleanly on my Allen key with zero stripping, even torqued down to spec. Solid hardware for the price, will buy again when I need more.

The partially threaded design made these perfect for clamping down a fixture plate without the threads binding up prematurely. The hex socket drive seated firmly with my Allen key, no stripping or wobbling at all.
