GS 550 - Rear Shock Dome Nut?

[Guest]

Hi,

I was riding home and noticed my rear shock dome nut had dropped off.

I ordered a M10 Dome nut, metric thread.

However, as I put it on - the threads did not match. I have now damaged the bolt. :-( - see picture

What is the correct dome nut? Is it UNC thread?

Can the bolt be replaced? I think it's welded to the frame?

many help would be appreciated

Its a 79 GS550E I believe.

cheers

M10 fine pitch (1.25, not 1.5). A thread file or die will clean up that stud.

Your next task should be a walk-around with wrenches and screwdrivers in hand checking for other loose/missing connections.
As 922 mentioned, those threads look repairable.

I could fix those threads with a small triangular file in 2 or 3 minutes and you wouldn't even be able to see the damage. Run a correct die over them even quicker.

Also might be good idea to use loctite threadlock on your nuts and bolts as you check other bolts!!
