Kluson machine tuner (parts)

Take one of the other screws off of its tuner and head to a hardware store. After matching the screw, find some one with a rock tumbler and have it tumbled for a few minutes. In you position I would even consider replacing all tuner screws so they match if a slotted screw isn't available.

 

The screw is a 12-24 x 3/8" slotted round head machine screw. I work with that series of Klusen tuners all the time, because they are also used on the Ampeg Scroll Basses and Baby Basses. The screws you'll find at the hardware store will be zinc plated. If you buff up the head, it will look pretty close to nickel. I also have some that I've had nickel plated, but they are shiny, not distressed.

 

That is such a common screw sized I'd be surprised if you couldn't get them in stainless, don't know which would look closer though.

 

Yes, you can easily get these screws in stainless too. That's certainly an option. Stainless, buffed up, is a little different in color from buffed nickel. But it may be easier to age and distress the stainless with some kind of mild acid.
