M30-3.5 X 100mm 六角頭螺絲 | 10.9級鋼黃鋅鍍層 | 全螺紋 (5顆/包)

Needed to replace some critical bolts on a large press and these M30s threaded in smoothly with a socket. The yellow zinc finish looks solid and the 10.9 grade gives me confidence they’ll hold up under heavy load.

Wrenched these onto a heavy equipment frame and the hex head sat perfectly in my socket, no slipping at all. The zinc finish looks clean and the 100mm length was exactly what I needed. Five bolts is a decent little pack for the price.

The yellow zinc coating is uniform and looks clean on my equipment assembly, and the fully threaded length made alignment effortless. These M30s seated squarely with a socket drive and held firm at the rated torque class.
