I was adjusting the intonation on the saddle and the A string saddle is stripped out. I cant tighten or loosen it. Maybe its the saddle, or the screw. Can I buy these anywhere?

Here are the part#'s-

Hi cpgamer: any Fender part can be ordered from any Authorised Fender Dealer. Just take the part number, as provided by YZFJOE, and order the item. Or type "genuine Fender parts" into Google and you will find numerous online stockists who will have what you want.

Do you need a whole new saddle or just the screw? If the latter, be aware that they come in different lengths for the different saddle positions...

Sounds like you didn't release the string tension before adjusting them. They really should not strip out unless the guitar is very abused and the hardware is all rusted. When you adjust the intonation, you will have to retune the string anyway. The only part on a guitar that is made to be twisted on while there is tension on the strings is the tuners, just a reminder for all those not exsperienced with working on their guitars.
