For anyone that is having trouble with nuts coming loose this may be the answer. I have not tried them but this video looks good:

Thanks for the info Bill....very cool video!

Looks perfect for the screw holding in the spark arrestor/silencer insert! The operating principle shouldn't be degraded by heat. Nifty. I wonder if they make 'em in 4mm size?

A quick look found M3 & M5, plus a bunch of 'Merican sizes. Cool item, someone should buy a batch & sell them off in small quantities (Paul? Bill?)

DOH! . . . and the screw to retain the silencer innards is 5mm (not 4 - should have looked it up before posting).

In searching around I see that even Walmart and Amazon have some sizes available online in packs of 10 and 20.

That is unbelievable, how huts can loosen and what a video that shows how the washers work. And thanks BC------------ Clarence
