This is a pack of ten Klinik M3 Thread Repair Inserts, an awesome fix for stripped out threads anywhere 3mm screws are used. These parts are machined out of brass and expand when the screw is installed. The outer knurls grab tight onto plastic and increases strength 2-3x over plain screw threaded directly into the plastic. A dab of CA upon installation secures them even further.

For installation, drill stripped holes with a 5/32 bit, being very careful not to remove too much material. Keep the drill bit inline with existing hole, and use slow speed. Press repair insert into plastic with knurls inserted first until flush with surface. You can use a drop of CA glue on outside of knurls to create an even stronger repair. Be careful to not spread glue to internal threads. Voila! Done!
