براغي رأس سداسي M10-1.5 × 60 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولب جزئيًا (100 / عبوة)

Used these to mount a heavy motor bracket to a steel frame, and the class 8.8 grade held up perfectly without stripping. The zinc plating seems solid too, no rust after a few weeks in a damp garage.

The partially threaded design made it easy to tighten these down on my equipment mounting bracket without binding. The zinc coating looks clean and the hex head fits my socket perfectly.

Forgot to measure first time—these are slightly shorter than the random bolts I had on hand, but the partially threaded design grabbed perfectly. The zinc coating looks solid and the hex head fits my socket snugly.
