What is a pneumatic nail gun used for?
Answer: Rapidly driving nails using compressed air
A pneumatic nail gun (also called an air nailer) uses compressed air to drive nails into wood or other materials with speed and precision. It dramatically increases productivity compared to manual hammering and is used extensively in framing, roofing, and finish carpentry.
What is a multimeter used to measure?
Answer: Voltage, current, and resistance
A multimeter is a versatile electronic measuring instrument that can measure voltage (volts), current (amperes), and resistance (ohms). Many multimeters also measure continuity, capacitance, frequency, and temperature.
What is the purpose of a C-clamp?
Answer: Holding workpieces firmly together or to a surface
A C-clamp (named for its C-shaped frame) holds workpieces firmly together or secures them to a worktable during gluing, welding, drilling, or other operations that require the work to remain stationary.
What is the purpose of a stud finder?
Answer: Locating wooden or metal framing studs behind wall surfaces
