M18-2.5 X 85mm 外六角螺絲 | 316不鏽鋼 | 全牙（10入/包）

Installed these on a marine gate latch and the threads bit perfectly without any galling, which I've had with cheaper stainless bolts. The hex heads held torque nicely with a standard socket.

Pulled the thread cleanly with a socket on some heavy frame work, and the 316 stainless feels like it’ll shrug off our salty shop air. Fully threaded down the whole 85mm, so I didn’t need extra spacers. Minor gripe: the pack count is exactly ten, no spares, but they’re solid enough that I won’t mind

The hex head on these M18 screws seated perfectly in my socket wrench with no slipping. They replaced some old bolts on a piece of farm equipment and the 316 stainless seems like it will hold up well to the weather.
