Question 1

Which tool is used to measure the angle of a surface relative to a reference without using a protractor?

Accepted Answer

Bevel gauge (sliding T-bevel)

Question 2

When tightening a bolt with a torque wrench, you should:

Accepted Answer

Answer

Feeler gauges are thin metal strips of precise thickness used to measure narrow gaps such as spark plug gaps or valve clearances.

Accepted Answer

Drift punches are used to align holes in mating parts, not to start drill holes

Answer

A drift punch (aligning punch) has a tapered body used to align bolt holes in plates or flanges before inserting fasteners.

Question 5

Which hacksaw blade TPI (teeth per inch) is correct for cutting thin-wall steel tubing?
