I was unscrewing this bottle cage bolt and it doesn’t screw in anymore. Does anybody know how to fix this or if a LBS will charge a lot to fix? Super annoying since I can’t mount my bottle here.

Is this a new bike?
I would try screwing a well-greased *steel* screw in there first and see what happens. This’ll likely clean up the threads.
If you’re able to get it in and have it hold, then just use a new bottle cage screw and all will be good.
(Aluminum screws are a weight saving thing and I don’t like it; the screws strip too easily. But at the same time, they keep the rivnut from stripping…)
I would take it back to the dealer you purchased it from. If it’s brand new it should be covered by some sort of warranty.
That sucks man. Would take this to someone who knows how to tap new threads. You may have to bore out the bottle cage mounting hole to accomodate a bigger bolt depending on how wide they’ll need to go.
If its a metal frame you can bring it back to the shop and they will chase the thread with a threading tool. If you got it online just buy a cheap tap and try it.
Try a different bolt (steel) or just take it back to the shop you bought it at.
What is this screw, is it the correct screw for the hole? Looks like you pulled the threaded rivet out of the socket?!
I’d say the silver threads SHOULD look like the black threads. They have been smashed and are effectively useless. Hopefully the threads in the frame aren’t wrecked.
Is the with the bolt of the braze on? Have you tried screwing a different bolt into it?
Damn, that thread looks fucked.
Anyways, Measure the hole and step-up a Thread (M5 or M6).
If you want to use a M5 Screw, you have to drill a 4,2mm hole. For a M6 Screw you need a 5,0mm hole. After you drilled a Hole, take a Thread Cutter/Tap (M5 or M6), put a bit of oil on the tip and cut that mf a new thread. Done.
Should take about 15min max, if you have never tapped a thread before. I assume your bile frame is Aluminium, so it should be a fairly easy job. Equipment cost is maybe 10€.
I‘m from Germany, so I apologize for possible mistakes regarding my English. I also work as a mechatronics engineer, if that helps.
My giant came with all the bottle screws jacked up. They had to retap them.
bro that brick wall looks like something that dead girl crawled out of in the Ring…
You could try a Helicoil
