I recently bought a lathe. Part of the promotion was an LED light. I

found the holes in the headstock are incorrectly tapped. The mounting
location on the tailstock are correct. I really don't want it on the
tailstock.
The incorrect holes are drilled/tapped M3.5x.35mm. They should be
M4x.70. M3.5X.35 is a "standard" M3.5 fine thread but these things
are unicorns. I haven't found them anywhere, including Amazon,
Grainger, Bolt Depot, and Fastenal.
Have you looked at McMaster-Carr website? Left menu - select what you're looking for, see what they have.
