براغي رأس سداسية M6-1 X 85 مم | فولاذ فئة 8.8 مطلي بالزنك | خيط جزئي (200 / عبوة)

Opening up the box, I was glad to see the zinc plating is even and clean across all 200 pieces, no rust spots or scratches anywhere. The hex heads fit a standard socket perfectly, and the 85mm length with partial threads worked great for bolting two steel plates together without the threads chewing

The partially threaded shaft made these perfect for securing a clamping block while leaving room for adjustment. Threads were clean and the zinc coating looks even across all 200 pieces.

Used these on a jig fixture that gets constant vibration, and the zinc plating still looks fresh after a week of use. The partial threading made alignment much easier than fully threaded bolts in tight spaces.
