Powder-Actuated Fastener
Powder-actuated fasteners are nail guns used by carpenters to attach wood to concrete and are used to frame out closets and other small rooms constructed inside previously built rooms. They were developed during World War II to help Navy seaman make quick repairs to the hulls of ships. The technology relies on a controlled explosion created by igniting a small gunpowder charge, similar to the process that activates a firearm. Warning: Operators of powder-actuated tools must be trained by instructors who are certified in the tools' use and storage. These tools pose an inherent danger beyond that of standard power tools because explosive charges shoot fasteners into concrete or steel. Powder actuated fasteners should only be used in dry, interior environments. They should never be used in explosive or flammable environments. And make sure the area is well-ventilated!
