Where can you buy a 3/64" Allen wrench?

...ordered the 10 pack so I can leave one in each engine I have...

I have 60-70 of this type of motor built starting in 1970, and not a single one has ever needed to have that screw turned. Don't do it unless you are fixing something that somebody else messed up and moved that screw.

Thank you very much, ADCX Rob!  I ordered the 10 pack so I can leave one in each engine I have. I have something like the Lucas stuff: I got the brand that Jim Barrett recommended and I use that instead of the Lionel stuff. It seems to work better.

However, don't take that screw out to lube the armature... just lift the entire brushplate off and place a tiny dab of Lucas Red 'N' Tacky #2 on the top of the shaft for a lifetime lube. The screw rarely needs any wear adjustment after the factory sets it.

I have several MPC engines which have the adjustable set screw you need a 3/64" Allen wrench to turn to adjust or remove to oil the armiture. I got one years ago at an Ace Hardware but they no longer carry them. Nor does anywhere else I tried including Micro-Mark. If the one I have breaks or I lose it I'm out of luck. Does anyone know someone who sells small tools like that? Thanks for your help
