Gbex says: Powder-actuated tool cartridges work similarly to blank firearm cartridges. In many cases, the charges are firearm cartridges with modified casings. The .22 Short, developed by Smith & Wesson is common. The powder is cordite.
These charges may be hand-fed, or manufactured and distributed on a plastic strip. The charges are activated when a firing pin strikes the primer, which is an explosive charge in the base of cartridge.
The primer ignites the cordite, which burns rapidly. The gases released by the burning of the propellant build pressure within the cartridge, which acts either on the head of the nail, or on the piston, accelerating the nail towards the muzzle.
Basically, powder actuated tools are some kind of a nail gun used in construction and manufacturing to join materials to hard substrates such as steel and concrete. Known as "direct fastening", this technology relies on a controlled explosion created by small chemical propellent charge, similar to the process that discharges a firearm.
Accordign to sources, powder-actuated technology was developed for commercial use during the Second World War, when high velocity fastening systems were used to temporarily repair damage to ships. In the case of hull breach, these tools fastened steel plates over damaged areas.
Powder-actuated tools come in either high velocity or low velocity types. In high velocity tools the propellant acts directly on the fastener. This process is similar to a firearm.

Powder-actuated tools come in either high velocity or low velocity types. In high velocity tools the propellant acts directly on the fastener. This process is similar to a firearm.
Low velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate. A powder-actuated tool is considered to be low velocity if the average test velocity of the fastener does not exceed 492 feet per second.
Powder-actuated fasteners are usually nails made of high quality, hardened steel, although there are many specialized fasteners designed for specific applications in the construction and manufacturing industries.
