براغي ذات رأس سداسي M12-1.75 × 70 مم | فولاد فئة 10.9 مع زنك أصفر | كامل الخيط (50 / عبوة)

The threads cut cleanly and the hex heads held up fine under torque with my socket wrench. Installed a dozen of these on a conveyor frame and every one seated perfectly without stripping.

Was a bit worried about the zinc coating holding up during a heavy equipment repair, but these fully threaded 10.9s torqued down without any stripping and the yellow finish looks uniform across all 50. They’re a solid deal for the price, and my wrench grabbed the hex head perfectly every time.

The hex head on these bolts fit my socket perfectly, no slippage at all during torquing. I’m glad I went with the 10.9 grade for this industrial shelving rack—definitely feels sturdy enough for the load.
