Wanted: Thumb Screw (Audax Electric Pickup/Extra Long)

[Zkeener323]

I am searching for a thumbscrew that will fit my Audax electric pickup. It seems to have the same threads as an RCA pickup from both of my Electrolas. However, it needs to be much longer. Right now I am making due with a thumbscrew from a Presto 5C cutting head so that might help someone understand what I am looking for in both length and thread pitch.

Best,
