M6-1 x 85mm 外六角螺栓 | 10.9級鋼鍍鋅 | 部分螺紋 (900 / 包)

The hex heads on these 85mm screws grab a socket wrench perfectly, no stripping even with my impact driver cranking them into steel frames. The zinc coating gives a clean, consistent finish that matches the rest of my hardware. Exactly what I needed for heavy equipment assembly, and the 900 count me

The partial threading on these M6-1 x 85mm screws is exactly what I needed for clamping two plates together without bottoming out. Zinc coating looks even and the hex heads seat cleanly in a socket wrench, no stripped edges across the first fifty I've used.

Got these for a batch of equipment repairs and the zinc plating is holding up nicely after a few weeks of shop use. The partial thread on the 85mm length gives good grip without bottoming out, and the class 10.9 steel feels plenty tough for my torque needs.
