M6-1 x 85mm 육각 머리 캡 나사 | 클래스 10.9 강철 아연 도금 | 부분 나사산 (900개/팩)

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.
