براغي رأس سداسية M33-3.5 × 150 مم | فئة 8.8 فولاذ مطلي بالزنك | خيط جزئي (12 / عبوة)

The threads caught perfectly on my equipment rebuild—way better than the generic bolts I've been struggling with. The hex head takes a socket easily, and the partial threading saved me from having to use spacers.

Installed these on a heavy press at the shop, and the zinc plating held up well against the grease and grime. The partial threading gave just the right grip without needing extra washers.

These threads are beefy, 150mm of solid class 8.8 steel, so they feel super secure when I'm torquing them down on my equipment. The zinc plating is smooth and even, and the partial threading is exactly right for clamping two thick flanges together.
