M22-2.5 X 60mm 外六角螺絲 | 10.9級鋼本色 | 全牙（70入/包）

The hex head made tightening these into place simple with a socket wrench, and the fully threaded length held securely in a heavy mounting bracket I was working on. For the price per package, you get a solid quantity of industrial-grade fasteners that feel durable right out of the box.

Used these for bolting down a heavy motor mount at work — the hex head gave a solid bite with a socket, and at 60mm length they reached through cleanly. Threads ran smooth the whole way.

Needed these for a heavy equipment repair and the Class 10.9 steel held up perfectly under torque. Fully threaded all the way down made alignment a breeze, and the hex heads grabbed the socket cleanly. Pack of 70 is solid value for the price.
