I have a Yamaha TRBX174 which is an inexpensive, passive PJ bass. Apparently the pickup screws are an unusual metric size wood screw, and they do not have replacements at the music shop or at the hardware store. I called Yamaha and they said the measurements of the screws are 2.6mm x 35mm. They said it would take a month to order them from Japan so they suggested I buy them from Stew Mac or Allparts. Neither of them carry screws in that size. Does any of this make sense? I'm not changing the pickups (yet) but I do want to swap out all of the screws because they're rusting and I've semi-stripped a couple of them. Any advice?
