Which tool is used to measure the angle of a surface relative to a reference without using a protractor?
Answer: Bevel gauge (sliding T-bevel)
A sliding T-bevel (bevel gauge) can be set to any angle from an existing surface and then transferred to another workpiece.
When tightening a bolt with a torque wrench, you should:
Answer: Pull the handle toward you in one smooth motion until the wrench clicks or deflects
A click-type torque wrench signals the set torque with a click; further force over-torques the fastener.
A feeler gauge set is most commonly used to measure:
Answer: Small clearances and gaps between parts
Feeler gauges are thin metal strips of precise thickness used to measure narrow gaps such as spark plug gaps or valve clearances.
What is the function of a drift punch compared to a center punch?
Answer: Drift punches are used to align holes in mating parts, not to start drill holes
A drift punch (aligning punch) has a tapered body used to align bolt holes in plates or flanges before inserting fasteners.
Which hacksaw blade TPI (teeth per inch) is correct for cutting thin-wall steel tubing?
Answer: 32 TPI
Thin-wall tubing requires a fine 32 TPI blade so at least two or three teeth are always engaged, preventing the blade from catching and stripping teeth.
A strap wrench is preferred over a pipe wrench when working on:
Answer: Polished chrome plumbing fixtures or plastic pipe
A strap wrench grips using a rubber or fabric strap that won't scratch or bite into polished or soft surfaces.
What does a scratch awl do that a pencil cannot in layout work?
Answer: Scribes a fine, permanent line directly into metal or wood
A scratch awl scribes fine lines into hard surfaces that remain visible and won't rub off, unlike pencil marks.
