Hi, the only place I can think of to get some information, the forum has helped with a couple of other inquiries over the years....
A friend gave me this, he was told it was from an RAAF F-111, titanium bolt is 100mm long from the flange, 20mm diameter, (would it be metric if itīs from a US aircraft?).
The thread should be longer if the spring lock on the īnutī should contact it so it is probably not for this bolt.
Any help appreciated, even if it is just saying what this type of nut was used for..... looks interesting, cheers, John
