براغي رأس سوكيت M12-1.75 X 35mm | رأس زرية بمحرك سوكيت سداسي | خيط كامل | فئة 12.9 فولاذ سبائكي مطلي بالزنك (100 / عبوة)

Installed these on a custom jig I've been building, and the zinc plating looks great while the hex socket drive makes tightening them with an Allen wrench really easy. They're fully threaded, so I didn't have to worry about engagement depth in the aluminum plate.

These hex bolts fit perfectly into my tooling jig setup, and the 12.9 grade steel feels noticeably tougher than the standard hardware I've used before. The fully threaded shaft made alignment a breeze, and the zinc coating seems like it'll hold up well in my shop environment.

The zinc plating looks even and clean, so these should hold up fine in my shop without flash rusting. The 12.9 hardness is reassuring for the jig I’m building, though the button heads are a bit shorter than I pictured for grip.
