براغي رأس أسطوانية M6-1 X 80mm | محرك سداسي داخلي | جزئية الخيوط | فولاذ سبائكي درجة 8.8 مطلي بالزنك (200/عبوة)

The zinc plating is holding up nicely so far, even after a week of daily use in my jig setup, and the threads cut cleanly into the steel. For 200 pieces at this price, they're a solid value.

I had to swap out a batch of shorter screws on my press tooling, and these 80mm ones with the zinc plating fit perfectly without any burrs. The hex drive makes installation quick and the 8.8 grade gives me confidence in the assembly's hold.

Needed exactly 80mm for a custom jig I'm building, and these fit the tolerance perfectly. The zinc plating looks consistent and clean across all 200 pieces, no burrs or defects.
