براغي رأس سداسي M6-1 × 75 مم | درجة 10.9 فولاذ مطلي بالزنك الأصفر | خيط جزئي (200 / عبوة)

Installing these on a piece of machinery this morning, the hex head gave me a good solid grip with my socket wrench without any slippage. The partial threading started cleanly and the 75mm length was spot on for my application.

I was worried about stripping the threads on my press jig, but the Class 10.9 steel on these bolts handled the torque without a hitch. The yellow zinc finish seems like it'll resist rust well in my shop too.

Needed a handful of these for a heavy shelving unit, and the partial threading really helped with the alignment. The yellow zinc coating looks clean and hasn't shown any rust after a few months.
