Glue and clamp..then..set it aside as a spare..I doubt you'll be happy keeping it..it will eat at you..causing psychology issues..you can't unsee it..staring at you..mocking you..

I recently heard that 54 strat..possibly Buddy Holly's that's now in Australia..whew..that's some good tones...his other 54 is excellent also...to my ear.. nothing new comes close to that original tone...

I have to leave you now..they need my help on another thread..something about vibrato issues.. I just know I can help..
It's so obvious.. there's nothing wrong with the screw..it's the guitar that's wonky...keep the screw..replace everything else..btw.. I have an online degree in superduper master luthiermanship...
They used to sell a build your own laser kit also..neighbor kid built one..used it to burn a hole in another neighbors tire on their station wagon..big fun!!
