There are definitely at least three diameter sizes of 1.75" long "neck screws" kicking around. I have some Genuine Fender Neck Screws! (ffft) that'll take a 1/8" for sure, then some others in a little bag (I swear they'd have come from Warmoth, unless they didn't) that sure look like a 7/64"... go ahead, tell me it doesn't matter.... :sad1: I had some really mongo ones I put on Spermy the Imprecision Bass, if I could remember where I'd got 'em I'd get more - the toothier the merrier, sayeth the Beav. :toothy12:
