Power actuated fasteners use a powder charge to drive a fastener into concrete, stone, or steel.

• A. True
• B. False
• C. It depends
• D. Not specified

Answer: (A)

Power actuated fasteners rely on the energy from a powder charge to drive the fastener into hard materials. When the charge detonates, it powers a piston that drives the fastener into concrete, stone, or steel, creating a secure fasten in masonry or metal surfaces. Because this energy transfer is the essence of how these fasteners work, the statement is true.
