Are the spring washers used on these XK exhaust manifolds (FG106X) finished in black oxide? Thanks for your help
Gene Kahn
Yes they are finished in black oxide.
FG/106X is a decodable ‘standard’ fastener, and when ‘standard’ there is no specific surface finish specified, thus the normal default black-oxide…
If these spring washers were plated, or some other special/non-standard finish then they would be allocated a C.xxxx prefix Jaguar Part No…

As always, thanks so much Roger
Roger, On the black oxide spring washers, do the have a square or round profile?
Thanks for your help, Gene Kahn
They are square, in section.
Square - as per Paul’s pic…
Great, thanks so much
