Repair must be first evaluated by identifying thread (pitch and size, metric or S.A.E.) and then correlated to proper tap or die, according to industry standards and instructor’s guidelines.

- What is the difference between a tap and a die?
- When drilling for a given thread size, how is the correct hole size determined?
- Is a tapping fluid always used when repairing damaged thread?
- Is there a pattern to follow when using a tap wrench?
