- Insert the correct-sized tap into the beginning of the threaded hole. Slowly turn the tap clockwise one quarter turn.
- Turn the tap counter-clockwise to remove any plastic shavings.
- Turn the tap another clockwise quarter turn, before turning it counter-clockwise as before. Repeat this process until the plastic thread has been fully rethreaded. Remove the tap and slowly install the screw/bolt into the newly-threaded hole.
Things You Will Need
- Tap and threads
- Make sure that the tap is inserted into the thread hole at 90-degrees to the hole and that the correct diameter tap thread is used. Note that the tap thread is tapered at the end to allow easier access into the hole.
