What type of materials can be used with powder-actuated tools for fastening?

Powder-actuated tools are specialized fastening devices that use explosive charge to drive fasteners into hard materials. The correct option refers to these tools being particularly effective with very hard materials like steel because they are designed to penetrate robust surfaces where traditional fastening methods may fail.

These tools are commonly used in construction environments for securing materials such as steel tracks, concrete, and masonry. The power behind the explosive charge allows the fastener to be driven into dense materials, making them ideal for applications that require a strong, durable bond.

While options regarding only using wood and drywall or soft materials might indicate some of the uses for traditional fasteners, they do not align with the capabilities of powder-actuated tools. Additionally, while plastic and rubber can be fastened in some scenarios, they do not tap into the primary benefits provided by these powerful tools, which is the ability to install fasteners into very hard materials effectively.
