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

Gotta have these for attaching your head, perfectly seats in your socket wrench for hassle free installation, you know you drop those puny stock ten mil nuts nine times outta ten tryin to get them on those cylinder studs so stop messin around and invest in these, saved me at least a month's worth of time and who knows how much asprin. At least buy one and use it to get the little guys on there

M7 1.00 only exists in this dimension if you are right with the Treatland. My junkpile friction-drive build is saved!!!

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.
