M30-3.5 X 280mm 육각 머리 볼트 | 클래스 8.8 강철 아연 도금 | 부분 나사산 (1개/팩)

Perfectly matched the 280mm length I needed for a heavy press repair — the partial threading gave enough grip without bottoming out. These bolts feel solid in the hand and the zinc coating looks clean and uniform.

I needed a partially threaded bolt for a heavy mounting bracket, and these M30x280mm hex heads fit the bill perfectly. The zinc plating looks clean and the class 8.8 steel feels solid enough for the job.

These are hefty M30 bolts, the zinc plating looks clean and the partial threading made it easy to start by hand before tightening with a socket. I used one to secure a heavy press base and the 8.8 grade gives me confidence it won't strip under load. Exactly what I needed for industrial assembly.
