Repairing Stripped Threads in Plastic

This method does work, but it's not 'instant'. Even though five minute epoxy is the material used, the repair is best left to cure overnight for a reliable result.

1) Blow out the stripped thread with compressed air so it's free of any dust or debris. Check that the screw is clean, that there's nothing stuck to it.

2) Run the screw into the stripped hole to check that the hole is deep enough to accept the full length of the screw, when whatever the screw normally holds in place isn't there. If the screw is too long for that, use a slightly shorter screw of exactly the same diameter and thread pattern for step '5)' following.

3) Mix up a small batch of five minute epoxy. Fill the stripped screw hole with it.

4) Wet the screw with WD-40. The screw must be wet all over but not dripping wet.

5) Run the screw all the way into the hole. Wipe away the squeeze-out and leave it overnight for the epoxy to fully cure.

6) The next day, the screw will be tightly in place but removable because of the WD-40 coating. Unscrew it slowly and you'll have a serviceable thread.
