Course: Basic Small Engine Repair (20109) > Section: Identifying Fasteners and Their Uses

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.

Process/Skill Questions:

- 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?
