براغي رأس سداسي M6-1 × 65 مم | فولاذ فئة 10.9 مطلي بالزنك | سن جزئي (200 / عبوة)

The zinc plating looks clean and uniform across all 200 pieces, no flaking or rough edges that I've seen on cheaper batches. The 10.9 grade steel feels properly hardened when torqued, and the 65mm length with partial threading gave me just enough grip for the frame joint I was assembling.

The partial threading on these M6-1 screws made alignment much easier during a recent equipment assembly project. They drove smoothly with a socket wrench and the zinc finish looks clean.

The zinc plating on these 10.9-grade screws looks clean and even, and the hex heads seated snugly in my socket without any stripping. Ordered the 200-pack for a machinery frame job and didn’t find a single dud in the box.
