guys,
I need some advice on my ttop-- I have a hard top that is screwed to the aluminum frame. several of the screws have become loose. I can't seem to screw them back in-- the holes seem to be stripped. I thought about epoxying the holes, but the problem is that the aluminum frame is hollow, so I don't know if I can get enough epoxy in there. Another idea, I guess, is trying larger screws. any advice?
thx

I had this problem before as well. I used a bigger screw and just before it seats, put a generous amount of clear fngernail polish on the threads and under the head of the screw. The fingernail polish is like lock tite and will keep it from backingvout but unlike epoxy, you will be able to break loose the fingernail polish.

You could always get the holes welded and retapped.

larger screws coated with 3M 5200. Whatever you do , don't be messy. Where 5200 lays, 5200 stays. I should be an ad writer for 3M.

Couldn't you use larger screws and 242 Locktite? You can still remove the screws with the 242.

Problem is the larger the screw the less number of threads in contact with the tubing sidewall.
When nothing else works, drill all the way though and put a nut on the back side.
I guess another piece of tube or small plate could be epoxied over the stripped hole and re-drill with original size hole?

Put a zip-tie in the screw hole, screw the screw back in, trim the tab of zip-tie off and there you go. Seems to hold up extremely well. No longer svrews needed, no re-drilling of holes. You could put some 5200 in the hole as well, put so far not needed.

The hard top on my boat is attached with stainless bolts drilled through the tubing and flat washer with self locking nuts on the bottom of the tubing. You might want to check to see if you have any wired ran inside of the tubes before drilling. Hope this helps.

Thanks to all for the advice. Ended up drilling through the bottom of the aluminum putting a longer bolt with a nut as suggested by a couple of you. Once again, the willingness on this site to help each other is wonderful. Thanks.
