Introduction To Nail Gun Fastening Technology

Nail gun fastening technology is a direct fastening technology that uses a nail gun to fire a nail barrel. The gunpowder in the nail barrel burns to release energy, and various nails are directly shot into steel, concrete, masonry and other substrates. It is used for permanent or temporary fixation of components that need to be fixed, such as pipes, steel structures, doors and windows, wooden products, insulation boards, sound insulation layers, decorations, and hanging rings.

The nail gun fastening system consists of drive pins, power loads, nail guns, and substrates to be fastened. When in use, put the nails and nail cartridges into the nail gun, align them with the substrate and the fastened parts, compress the gun to the correct position, release the safety, pull the trigger to fire the nail barrel, and the gas generated by the gunpowder pushes the nails into the substrate to achieve the fastening purpose.

What materials can be fixed with a nail gun? Theoretical and practical evidence shows that the substrate can include: 1. Metal materials such as steel; 2. Concrete; 3. Brickwork; 4. Rock; 5. Other building materials. The ability of a nail to fix in a substrate depends mainly on the friction generated by the compression of the substrate and the drive pin.

When a nail is driven into concrete, it compresses the concrete’s internal structure. Once driven into the concrete, the compressed concrete reacts elastically, creating a normal pressure perpendicular to the surface of the nail, which creates significant friction, holding the nail firmly in place and ensuring it is securely fixed in the concrete. To pull the nail out, the friction created by this pressure must be overcome.

drive pin

The principle of fixing drive pins on a steel substrate is generally that there are patterns on the surface of the nail rod. During the firing process, the drive pins cause plastic deformation of the steel. After firing, the substrate recovers elastically, generating pressure perpendicular to the surface of the drive pin, fixing the drive pin. At the same time, part of the metal is embedded in the grooves of the nail pattern to enhance the bonding force between the drive pin and the steel substrate.
