براغي رأس سداسي M12-1.75 × 85 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئياً (25 / عبوة)

The partial thread on these M12 bolts made aligning the equipment frame so much easier, and the hex heads grabbed my socket wrench cleanly without slipping. For 25 pieces at this price, they feel properly solid for Class 8.8 work.

The zinc plating is holding up nicely so far, and the partial thread made it easy to cinch down a flange without binding. I've got a few hundred left over for the next job, which is fine by me.

Used these to bolt a motor mount to a steel frame, and the Class 8.8 rating held up perfectly under torque. The zinc plating also looks clean and hasn't shown any rust after a week in a damp shop.
