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

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.
