Inner Door Lock Knob Thread

[Ol_Girl_58]

Hi all,

Can someone please tell me what thread the inner door lock knobs are? Are they 6-40 thread (like 55-57 Chev) or 10-24 thread, or none of the above? Reason being I've found some you-beaut billet knobs available in the above thread dimensions, but I don't know what FE-FC thread dimensions are. I hope I've explained myself well enough.

Thanks in advance,

Josh  :)

Hi Josh,

6-40 diameter is 0.138" x 40 TPI (UNF)

10-24 diameter is 0.190" x 24 TPI (UNC)

Hope this will help.
