Nail gun

A powered tool that drives nails into wood or other materials using pneumatic, electric, or fuel-powered force. It speeds repetitive fastening compared with striking nails by hand.

Connect

Pneumatic tool: A tool powered by compressed air delivered through a hose or built-in compressor. Many nail guns use compressed air to drive a piston that propels each nail.
Framing nailer: A nail gun designed to drive large nails used in structural wood framing. Its power and nail capacity suit wall, floor, and roof framing.
Nail (fastener): A slender metal fastener driven into materials to hold them together. A nail gun is built around driving nails of compatible sizes and types.
Hammer: A hand tool with a weighted head used to strike, drive, or shape objects. A hammer drives individual nails manually, unlike the powered tool's rapid repeated firing.
Occupational safety and health: The prevention of work-related injury and illness through safer practices, equipment, and working conditions. Nail-gun use is a workplace hazard requiring training, protective measures, and safe procedures.
Combustion-powered nailer: A nailer that uses a small fuel charge ignited inside a combustion chamber to drive a fastener. This fuel-powered design works without an air hose or electrical cord.
Finish nailer: A nail gun that drives relatively small finishing nails for trim and cabinetry. It fastens visible finish work with smaller holes than framing nails leave.
Collated nail: A nail joined to other nails in a strip or coil for feeding through a powered nailer. Collation lets the tool load and drive nails repeatedly without hand-feeding each one.
Screw gun: A powered tool that drives screws into materials using rotational force. Screws provide different holding and removal properties than nails driven by nail guns.
Nail gun safety: Practices and safeguards that reduce injury risk when operating or maintaining a nail gun. Accidental discharge and contact injuries make safe handling central to using the tool.
