What is the primary purpose of a micrometer?
Answer: Making precise measurements of small dimensions
A micrometer (or micrometer caliper) is a precision measuring instrument used to measure small dimensions with high accuracy, typically to 0.01 mm or 0.001 inches. It uses a calibrated screw mechanism.
What type of wrench is adjustable to fit different sizes of fasteners?
Answer: Crescent wrench (adjustable wrench)
A crescent wrench (adjustable wrench) has a movable jaw that can be adjusted to fit various sizes of nuts and bolts. The worm gear mechanism allows the user to open or close the jaw width as needed.
What is a ball-peen hammer used for?
Answer: Shaping metal and setting rivets
A ball-peen (or ball-pein) hammer has a flat face on one side and a rounded (ball) face on the other. It is primarily used for metalworking — peening (shaping metal by hammering), riveting, and rounding edges.
What tool is used to measure both inside and outside dimensions, as well as depth?
Answer: Vernier caliper
A vernier caliper can measure outside dimensions (using the external jaws), inside dimensions (using the smaller internal jaws), and depth (using the extending depth rod). It typically reads to 0.02 mm or 0.001 inches.
What is a tap used for in mechanical work?
Answer: Cutting internal threads in a hole
A tap is a hardened cutting tool used to create internal threads (female threads) inside a pre-drilled hole. It cuts matching threads that allow a bolt or screw of the corresponding size and pitch to be threaded in.
What is the purpose of a feeler gauge?
Answer: Measuring small gaps and clearances
A feeler gauge is a set of thin metal blades of precisely known thicknesses used to measure small gaps and clearances between parts. Each blade is marked with its thickness, and combinations can be stacked for intermediate measurements.
