A ball-peen hammer differs from a claw hammer primarily because it:
Answer: Has a rounded peen for striking punches and peening metal
The ball-peen (or ball-pein) hammer has a rounded head opposite the flat face, designed for striking chisels, punches, and peening (shaping) metal.
A feeler gauge is used to measure:
Answer: Small gaps or clearances between parts
Feeler gauges consist of thin metal blades of precise thickness used to measure gaps such as spark plug gaps or valve clearances.
What does a spanner wrench (hook spanner) do that a standard wrench cannot?
Answer: Turns round nuts or rings with notches or holes, not hex flats
A hook spanner or pin spanner engages notches or holes in specialized round nuts found on bearing lock nuts and lens rings, which have no hex flats.
When would you use a countersink bit rather than a standard drill bit?
Answer: To create a conical recess so a flat-head screw sits flush with the surface
A countersink bit cuts a cone-shaped recess that matches the underside angle of a flat-head screw, allowing it to sit flush or below the surface.
Which tool is used to remove a damaged or broken screw that has no usable head?
Answer: Screw extractor (EZ-Out)
A screw extractor has reverse-spiral flutes that bite into a broken fastener when turned counterclockwise, allowing the broken piece to be removed.
A dial caliper is preferred over a standard steel rule for measuring because it:
Answer: Provides higher precision with a dial readout to 0.001 inch
A dial caliper uses a rack-and-pinion mechanism to display measurements on a dial, providing precision to 0.001 inch versus the 1/16-inch typical of a steel rule.
What is the correct tool to use when you need to cut a piece of conduit or thin-wall pipe cleanly without a saw?
Answer: Pipe or tubing cutter
A pipe or tubing cutter uses a hardened wheel that scores and cuts through tubing with a clean, square edge as it is rotated around the pipe.
