Nailer

A nail gun or nailer is a type of tool used to drive nails into wood or som other kind of material.  It is usually driven by electromagnetism, compressed air or highly flammable gases such as butane or propane.  nail guns have in many ways replaced hammers as tools of choice amongst builders.

Nail guns often do not use individual nails. Instead, the nails are mounted in long strips (similar to a stick of staples) or in a plastic carrier coil, depending on the design of the nailgun. Smaller nail guns are often called brad nailers, bradders, or pin nailers, and drive nails with no head. Finish nailers drive smaller gauge nails, over a wide range of lengths, with very small heads.  Roofing nailers, almost always coil-loaded, drive large headed nails that decrease the risk of the nail tearing through the material being secured. Nail guns also have many advantages over hammers as they quickly and repeatedly drive the fastener and consistently set the nail head at, or below, the surface.
