Problem with 4 bolts that hold adio in

I have taken my radio out a few times and the four bols are not holding anymore the bolts will not tighten. Any ideas on what I can do? When I grab the bolt I can push it all the way into the hole and pull it back out. It isn't tightening

 

I don't remember for sure but if you look either you're completely stripped the holes or if it had the little clips they've come out. I don't remember if those used the clips..

 

The two top bolts do tighten... The bottom ones are loose... You can pull both bolts out easy.... Any ideas on what I can do?

 

No clips

 

Bump

 

Nice 17 min bump... I've never had this problem but first thing I'd try would be a couple layers of teflon tape on the screw to see if that gives you better hold on the threading.

 

Why do you keep taking the radio out? Just curious.

 

Look into the hole...are there threads or not?

 

post pics?

 

Sounds like you stripped the holes out.. Tap and die kit will fix it.

Or force a little bit bigger bolt in there.

 

Get a tap next size up ( metric )and rethread holes and install new bolts. Don't tap holes very deep ( 1/4 inch ). Could damage internal part in radio.
