metric COUPLER nuts
metric coupler nuts


coupler nut size


metric coupler nuts. very handy for certain things. use em for engine stud nuts. connect two bolts. lots of uses. im gonna get 4 M6 coupler nuts and put em on my magnum. then i'll never need a 10mm long socket ever again. so if i need to give my head a little tighten up on the go, no problem, i can use any 10mm socket!

zinc plated

I have these in place of regular heat nuts. kept stripping the normal sized nuts on long runs. Installed these in place and have never stripped one.

For peace of mind, they're worth it. I hate stripping stuff, especially stuff like cylinder studs, so i got these for peace of mind. Tons of threading area.
