So i changed the strings on my Ibanez a few days ago, and when I was trying to screw the knut lock for the E and A strings back in, I realized that the inside of the screw has gotten chipped away a bit, so the allen wrench won't fit in properly. Might my local music shop have the right screw, or will I have to go to guitar center, or perhaps even call Ibanez to get a new one?

Thanks for the help guys.
