Repair should include
- identifying the thread geometry (i.e., depth, diameter, pitch)
- selecting the appropriate repair and replacement method
- selecting the appropriate repair tools and fixtures (e.g., tap, wrench, die, thread-cert, Heli-Coil)
- performing the repair
- testing effectiveness of the repair.
Process/Skill Questions:
- What causes the hole to have to be repaired?
- What are the different thread pitches? How can one tell which thread pitch to use?
- What is cross-threading? How can it be prevented?
