براغي ذات رأس أسطواني M12-1.75 X 110mm | محرك سداسي | خيط جزئي | فئة 12.9 فولاذ سبائكي مطلي بالزنك (25 / عبوة)

The hex socket drive seated perfectly on my wrench without any wobble, and the 12.9 alloy steel feels reassuringly solid for a 110mm bolt. Threads ran smooth all the way into my jig fixture, no binding or grit.

Needed a full set of hardened bolts for a custom jig build, and these 12.9s didn’t let me down. The zinc plating is smooth and even, and the hex socket seated perfectly with no wobble on the driver. They’re a solid upgrade over the random bin bolts I’d been using.

The 12.9 alloy steel feels incredibly solid compared to standard hardware, and the partially threaded design makes alignment in jigs much easier. Fit perfectly into my fixture block without any wobble, and the zinc coating seems durable.
