براغي رأس سداسي M10-1 × 50 مم | فولاذ فئة 8.8 مطلي بالزنك | كامل الخيوط (100 / عبوة)

Perfect fit for mounting a heavy-duty jig I just built — the hex heads grabbed my socket without slipping. Needed a full 50mm length for through-bolting; these threads ran smooth the whole way.

The zinc plating is consistent across all 100 screws, and the class 8.8 steel feels plenty sturdy for the equipment frame I bolted together. They threaded cleanly into tapped holes without any binding. Packed well enough that the threads arrived untouched.

Pulled these out to bolt a conveyor guard back on, and the zinc plating kept them from rusting even though I left the box open in the shop. The hex head seated perfectly with a standard socket, no rounding at all.
