Bolt-firing tool

A technical device of fastening technology is called a bolt-firing device . These devices with pyrotechnic energy generation are used to set bolts or nails , staples (e.g. in drywall construction ).
The driving-in energies (“setting energies”) for powder devices are up to approx. 350 J on concrete and up to approx. 600 J for use on steel.
Current bolt-setting technology
The principle of the drive is somewhat similar to that of a firearm : however, the pyrotechnic expansion energy drives a piston instead of a projectile . This piston hits the bolt or nail (pistol → projectile ). This elastic shock transfers the energy to the bolt or nail. However, the piston never leaves the device: in the event of emptying or setting on too soft a surface or with excessive energy, it is prevented from exiting the device by a piston stop ring or a piston brake. This is the main safety difference to the previously widespread nail guns, which shot the nail like a projectile at high speed.
Earlier nail guns
Today, nail guns are banned in Germany by trade association regulations, but nail guns are very common. The latter have been within the scope of the EU Machinery Directive (2006/42 / EC) since 2006, are to be regarded as machines in the EU, EFTA and Switzerland and are not subject to weapons law. Bringing them onto the market requires CE marking or CE conformity. The safety requirements for CE conformity of powder-operated powder-actuated tools are described in the harmonized European standard EN 15895.
Colloquially, the battle gun is also referred to as a bolt gun. With the battle gun, the bolt extends and retracts, it does not leave the device.
