This is the place where the majority of the warbird (aircraft that have survived military service) discussions will take place. Specialized forums may be added in the new future

I'm working on a Canberra TT.18 project and would like to ask if anyone knows what thread design the hardware used. We can't seem to match anything in SAE or metric and some fractional wrench sizes (especially smaller sizes) don't quite fit. Would it have been built with Whitworth or British Standard Fine? Anyone have a parts manual that would indicate hardware description?
Thanks

It would be worth posting the question on the Flypast Historical Forum. I think you'd get a very quick answer!

It's a long time since I put a spanner to a Canberra but if I recall, the thread sizes were BSF/BSC & UNF/UNC; with Imperial A/F spanner sizes.

You might consider re-tapping with something close so you can use common hardware, especially for a static restoration.

Thank you for the reply's everyone. Disappointed with the Key Publishing "Aviation Forum". Applied 9 days ago, sent 2 contact emails and still not able to post and no reply to emails. Appreciate the management of this site.

Don't despair Carseneau, there is probably a glitch between computers or firewalls etc. I had a similar issue with a militaria site where a fella collected aircraft seats and I tried to join the site to contact him. Never resolved that one. But a month later I had a similar issue in a different website with different rare parts, but I had been a lurker there for the past year and lucked out with a fella who posted there used the same screen handle here on WIX. I contacted him and he alerted the mods and solved the issue. Find one of the Key publishing guys who post here and ask him to let their mods know the issue and pass on your e-mail so they can contact you or look for your app in their dump...or wherever you've been lost. Good luck!

It's a bit late to reply but due to the age of the aircraft I would expect to find BSW/BSF and BA fixings as previously mentioned.
I suggest the easiest thing to do would be select a few nuts or bolts at random and measure them with a vernier or micrometer. Wiki has the sizes - note they're specified by thread size, not head size so a 3/8"W spanner or wrench is approaching 3/4" A/F. BA fixings are numbered - 2BA, 4BA, etc.
If they are BSW/BSF and BA, as the British motor industry used them until the 60s, companies specialising in classic British cars may be able to supply tools.
They'll be easier to find this side of the pond but that doesn't help you.
