Stripped Screw-hole

Category: Multipurpose
Solution: When a screw-hole has become stripped, instead of re-drilling the hole, insert a small and thin object (a match stick for a wooden hole or a piece of solder for a metal hole) and screw back in the screw. This will carve threads into the inserted object.
Alternative product used and cost: Minimal
Result: Creates a tight seal without having to re-drill the hole.
Duration: Permanent if the screw will not need to be taken out again. If the screw needs to be removed later on, the inserted object may need to be replaced.
Original Options: Buy a tap or a drill and new screws and re-drill the hole.
Origin of AU (Alternative Usage): A classmate of mine has used this trick for many reasons, like attaching a wooden door to a hinge.

Origin of AU (Alternative Usage): A co-worker of mine said he has been doing this for a long time and says it is quick, easy, and effective.

Welcome to Alternative Usage

This blog will be helpful to some, and interesting to others. A new post will come every week with a new alternative usage for all sorts of products. Be prepared to be amazed by the kinds of things a product can be used for that it wasn't originally designed for. Contribution is encouraged. Everyone can benefit.
