6 Essential Facts About Nail Guns: History, Power, and Safety

Also known as a nailer, a nail gun is a handheld power tool that’s designed to drive nails into an object or workpiece. They are typically powered by either compressed air, flammable gas or electromagnetism. Rather than relying on a traditional hammer, a worker can use a nail gun to quickly and conveniently install nails. Even if you’re familiar with nail guns, though, you might be surprised to learn the following facts about them.

#1) Nailguns Emerged During the 1950s

The first nail guns appeared in the 1950s, introduced to construction firms primarily for flooring applications. Early models could drive 40–60 nails per minute and held roughly 400–600 nails per magazine, according to Wikipedia.

#2) Some Nailguns Are Powered By Explosives

Yes—some nail guns, known as power‑actuated nail guns, use a small burst of flammable gas to create a controlled explosion that drives the nail. This mechanism is distinct from the compressed‑air or electric systems most users are familiar with.

#3) Some Nailguns Operate With \"Bounces\"

Not all nail guns fire on trigger pull alone. \"Bounce‑type\" models require the operator to give the gun a quick tap—or bounce—against the workpiece while holding the trigger. The tool senses the impact and releases the nail.

#4) Nailguns Require Specific Types of Nails

Using the wrong nail can damage the gun or cause injury. Manufacturers specify the exact nail diameter, length, and head type (e.g., finishing, framing) in the owner’s manual. Always follow those specifications to ensure safe operation.

#5) Pneumatic Nail Guns Are the Most Common

Among the various power sources, pneumatic nail guns—powered by compressed air—are by far the most prevalent in commercial construction. A built‑in air tank propels the nail forward, providing consistent speed and torque.

#6) Safety Is Paramount

While nail guns speed up installation, they are a leading cause of workplace injuries. The U.S. Centers for Disease Control and Prevention reports that roughly 42,000 adults in the United States sustain a nail‑gun‑related injury that requires emergency treatment each year.
