What type of fastening tool is powered by compressed air?

• A. Electric tool
• B. Pneumatic tool
• C. Manual wrench
• D. Hydraulic tool

Answer: (B)

The answer identifies a pneumatic tool as the correct type of fastening tool powered by compressed air. Pneumatic tools use compressed air to operate mechanisms for applying force or motion, making them highly efficient for a variety of fastening tasks such as driving nails or bolts. This technology leverages the energy stored in compressed air to produce mechanical work, which is particularly useful in manufacturing and construction settings where speed and power are necessary. Electric tools, in contrast, are powered by electricity and do not rely on compressed air. Manual wrenches do not employ any powered mechanism; they rely solely on human effort to provide torque. Hydraulic tools operate using fluid (often oil) to generate power, unlike pneumatic tools that specifically use air pressure. Thus, pneumatic tools are uniquely suited for fastener applications involving compressed air, standing out among the other types mentioned.
