براغي رأس سداسي M16-1.5 × 45 مم | Class 8.8 فولاذ مطلي بالزنك | خيط كامل (50 / عبوة)

The zinc plating on these M16 bolts looks even and clean, and they threaded smoothly into pre-tapped steel without any binding. Used a dozen to mount a heavy jig frame, and the hex heads held up fine under my impact driver without stripping.

Finally got these for a heavy-duty bracket project and the hex head took a 24mm socket perfectly. The zinc coating seems decent so far, no rust after a few humid days in the shop.

Threads are fully cut end to end on these, so I could run them all the way through my fixture plate without any bottoming out. The hex heads seated fine with a socket, though the zinc finish started showing a couple of scuffs after a quick wrench-up. Solid enough for what I paid.
