Saddle Screws

[number six]

I lost a bridge saddle screw from my 4-string P bass that I built from parts.
The bridge saddles are either Chinese or Allparts and are threaded.
The screws are slotted head.
They measure 10.9mm x 3.2mm.
M3 x 12mm are too small and feed straight through.
M4 x 12mm are too large and don't go in at all.
#6-32 x 7/16" slot head, US standard threads, screw in a fraction but the thread is wrong.
My screws have twice as many threads as the US standard screws.

I've run out of options.
Any ideas please? (that don't include buying new saddles).

Figure out the actual correct size with one of these. May seem like a high price to figure out bridge screw threads, but you will find yourself using it anytime you need a screw size. I bought one 6 years ago. I use it way more than I expected to.

Some hardware stores have one at the store you can use if you do not want to buy your own. Trying to remember where I have used one in store. Want to say it was Rural King.

M3.5 ?

M 3.5 would be unusual indeed. Any large hardware store should have a thread size tool.

Perhaps for the time and hassle to find one screw...........just go this route.

Take one of your saddle screws to an ACE Hardware store and use their little plate full of threaded holes to find your screw size. If ACE does not have what you need, you will need to go to a Fastenal, Grainger, etc. if you don’t have an industrial supply within easy driving distance, go the web and google McMaster Carr. If they don’t have it, welcome to the wonderful world of Pac Rim fastener bingo. At that point it would be simpler to just grab a set of the saddles posted up by bassdude51

If the bridge isn't something special, I'd just get one from Amazon. I have wasted SO much time trying to find screws.

That 2125 saddle set is what I have! Allparts. The store I bought from here in Australia say Allparts think it's M3.5.
Can I find any slotted in Oz? No way.

Unless you just gotta have that bridge. I am sure there are plenty for sale on the classifieds here on TB.

I stopped in Music Go Round and the nice man let me root through his box of junk guitar parts. Found a machine screw for my MIM Tele bridge. {I did start with asking if they had a used bridge to sell and not with do you have any free screws}
