M8-1.25 X 45mm براغي ذات رأس مقبس سداسي | رأس مسطح بمحرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مطلي بالزنك (200 / عبوة)

I needed a batch of socket cap screws for jig assembly, and these 45mm ones with the hex drive fit perfectly without any stripping. The 10.9 grade alloy steel feels solid and the zinc coating looks uniform across all 200 pieces.

The zinc plating on these M8-1.25 x 45mm flat heads looks consistently smooth across all 200 pieces, no rough patches or flaking. I used them for a jig fixture and the Class 10.9 alloy steel torqued down firmly without any stripping on the hex socket.

The hex socket drive grips my Allen key perfectly with zero stripping, even on the third tear-down of my fixture. Zinc plating is uniform across all 200 and the 10.9 alloy steel feels properly hardened when torquing down.
