M30-3.5 X 230mm 六角頭螺絲 | 等級10.9 鋼 無處理 | 半牙 (2顆/包)

These bolts fit perfectly into the existing threaded holes on my press, and the hex head took a socket wrench with no slipping at all. The 10.9 steel feels noticeably tougher than the old hardware I replaced, and the partial threading made alignment much easier.

The partially threaded design made installation much easier since I didn’t have to thread the whole length through tight holes. These M30 bolts fit my heavy equipment assembly perfectly with a solid, secure feel using a standard socket. Definitely solid quality for industrial fastening jobs.

I was worried about finding bolts that would hold up under heavy torque, but these M30x230mm hex heads bit clean and the partial thread made assembly much easier.
