By epoxying the hole and not just covering over the.
Storm door screws stripped.
And often the mounting screws strip and loosen from heavy wear.
And any longer screw at the hardware store will work.
Fixing the problem used to involve the tricky job of patching the old holes or even splicing in new trim.
Number one get a safety chain for the top of the door so that it stops the door at 90 degrees and doesn t yank or bend your closer.
Any hardware store should have them.
Pre drill the aluminum to the outer diameter of the threads so that there s no grab on the way through and pilot the door slightly smaller than the screw shank.
If it s the hollow part of the door then your only option is to use a larger thread screw if the metal is solid all the way in then you can machine tap the hole with the next size larger and use a new screw.
A heavy wind can catch a storm door and whip it open like a sail tearing out the closer mounting bracket and cracking the door frame.
Since the sheet metal the door is made from has been stripped out it s likely you don t have enough material left for the screws to bite into.
The wrong way is a temporary fix not cool.
Fix it the right way not the wrong way.
