In replacing my exhaust (which I did before 18 years ago!), I find the
two halves of the pipe clamp connecting the front pipes to the down
pipes have regular split lock washers and regular nuts. Yet, the manual
warns that these should not be overtightened and the use of the sealing
rings (olives) suggests some movement anticipated as the exhaust moves
up and down.
The Parts Catalogue appears to show the use of one flat washer and nylon
lock nuts here but, will the nylon stand up to the heat?

Gene,
The locknuts that would go on an exhaust would be the split or
crimped steel locknuts…
In my experience VW is the only manufacturer that does this…
Every other car that I have worked on usually has brass nuts, not locknuts,
or regular steel ones for the manifold to headpipe…
Cheers,

No. It’ll melt right out of there. Ask me how I know

Sorry Gene,
These split top nuts were used in the aircraft industry long before nyloc
became available, probably in the early 70’s from memory.
Anyway if you look up “Industrial fasteners” in Yellow pages and ask a
supplier for these I am sure they can help. They will probably send you a
few a free samples, just quote the thread size, 5/16" UNF probably but check
this.

Thanks! I ordered them to see what they are but, what would be the heat
limitation? Where did you get that figure? Do you mean that the metal melts at
450 degrees?

Don’t shoot Gene, I’m just the messenger! The catalog is where I got the figure.
I am guessing that at that temperature, the metal expands enough to negate the locking
effect. Either that, or they are made of paper and catch fire at Fahrenheit 451.
BTW, they say Nylocks are good to 250 degrees F.
