Short string height screws for Fender JB - where to buy?

Hey fellow bass players,
I did some search and didn't get an obvious answer, so sorry it it's been answered before. The standard string height screws in the bridge of my MIA jazz bass are ruining the side of my hand. I need to replace them with a shorter version. I think standard are about 1/2" (10-12mm?) long. I need them half that length. I think 1/4" would work perfectly.
Can anyone point me at a resource, or better, direct link where I could buy those suckers? Does Fender make them (I looked, didn't find)? If yes, what's the fender part number?

Greatly appreciated.
 
I'm thinking you'll likely need to modify whatever you get - I've never seen such a thing for sale. Maybe best to modify what you already have if you have any DIY skills. Then again, maybe an expert will show up with a supply link :).
 
I second taking one to a store except I would go to a specialty place like Fastenal or Grainger. While you are at it get them in stainless steel. I've done that with my fenders and corrosion is a thing of the past. That really helped because here in Florida by the ocean we do lots of hot and sweaty outdoor gigs.
