WTB a set screw for precision bass machine head gear pinion

MikeDearing

Does any one have a Broken machine head ( sometime ears have fallen off the peg...  or a spare said  cross head screw that fits into the gear  pinion ( it screws into the tuning post to make certain they are attached )  - this is an American precision from the 60s....,,  but rather mysteriously the screw in the back of the D machine head disappeared !  Not too worried if it is  brighter more modern looking chrome -  it serves function rather than vintage correct  I have a picture of said issue for reference if anyone has something to help !  There is a wonder whether the shaller F replacement has the same thread but £35 for one including  postage is a lot for one screw especially if it's metric  ! And the posts look decidedly chunkier in diameter   Cheers Mike.   It's like the for want of a horse shoe nail analogy - very irritating

I shall have a rummage. A photograph illustrating the screw thread would help.

Ok doke I'll do a pic of one of the others  ping me a message with an email and I'll ping it to you.. I'm certain  it will be quite a fine thread from memory - like BSF/BA or cycle but US and def imperial - it's a  sixties bass

There are many different threads for these, and a modern replacement won't fit - as you say it has to be the original US type (I forget what the thread description is).

They have a habit of falling out - if they're even slightly loose, the vibration from the strings over time will gradually undo them. It's best to thread lock them into place.
