Powder-actuated tools are specifically characterized by their use of gunpowder cartridges to drive fasteners into hard materials, such as concrete or steel. This method allows for a rapid and forceful application of nails or anchors, making these tools particularly effective in construction and industrial applications where traditional fastening methods would be impractical or time-consuming.

The defining feature of these tools is their mechanism of action; they utilize small, controlled explosions to propel fasteners at high speeds. This distinguishes them from tools powered by other means, such as electric or pneumatic tools, which do not involve the combustion of gunpowder. As a result, powder-actuated tools provide a unique advantage in terms of portability and ease of use in environments where power sources may be limited or unavailable.

In contrast, the other options describe different types of tools or fastening systems that do not employ the gunpowder cartridge method, highlighting why they do not align with the definition of powder-actuated tools.
