براغي رأس سداسي M6-1 X 25mm | درجة 10.9 من الصلب مطلية بالزنك | ملولبة بالكامل (500 / عبوة)

I used these to rebuild a small machine jig, and the hex heads gave my socket a solid bite every time. The zinc coating looks uniform, no flaking.

The threading is clean and consistent across all 500 pieces, which made assembly on my equipment frame go without a single stripped bolt. Zinc plating looks uniform and should hold up fine in a dry shop environment.

Finally found a bulk pack of M6-1 screws with a clean zinc finish that doesn’t flake off during installation. The 25mm length is perfect for securing brackets in my shop, and the hex head gives a solid grip with my ratchet.
