Screw gun

A screw gun is similar to a power drill, but designed specifically for driving screws. A screw gun looks like a drill, but has a "nose" instead of a chuck. The nose holds an interchangeable 0.25 inches (6 mm) shank bit, commonly known as a tip. The most common types of tips are 1 inch (25 mm) #2 phillips, T25 Torx, and flatheads. The nose on either type of screw gun can be adjusted to countersink screws to the desired depth. The user must apply pressure to the bit to engage the clutch and drive the screws.

Types of Screw Guns

There are several types of screw guns, all of which operate very similarly with a few key differences. The basic drywall screw gun is used to run one screw at a time, then the user must place another screw on the tip before running another. Since the screw gun is a specialty tool, this type of screw gun is ideal for the everyday person that does not use the tool frequently and is not overly concerned about the speed of their work.

A Ridgid corded autofeed screw gun


Another type of screw gun is the autofeed, which automatically feeds screws from a clip, similarly to how a nail gun feeds nails. This style screw gun allows the user to run screws much easier and much faster. Since this type of screw gun only requires one hand for operation and has a clip, it would be perfect for someone working in the construction. Assuming the tool is set correctly, the user is able to screw until the gun bottoms out and each screw would be at the perfect depth. Some screw gun users keep the motor running constantly, which many manufacturers recommend while installing drywall.

The third type of screw gun is a collated screw gun that operate in the same manner as an automatic screw gun, however they have an extension that allows the user to stand while running screws. Although this type of gun may be more difficult to place the screws in a precise location, it allows the user to be much more comfortable while running screws at the same speed. These types of screw guns are capable of running screws well below the surface of the material and therefore have a variety of uses such as deck building, framing, furniture, and more. For those who may not want this specialty tool, there are also attachments that connect to a traditional power drill, that offers the same benefits.


Nowadays, all three types of screw guns can be found in corded or cordless variants depending on the manufacturer. Corded screw guns are stronger and can be used for an unlimited amount of time, however they must be plugged into a wall outlet. Although cordless screw guns are not as powerful and slowly run out of battery, they are more versatile as they can be used anywhere where 110 V power is not available or if cords are less preferred.

Screw Gun vs Power Drill vs Impact Impact Driver

Power drills are used to drill holes into materials and attach multiple materials with a variety of fasteners. Impact Impact drivers are used to tighten or loosen fasteners with a hammer that provides greater torque for more power. Although both of these tools are more versatile than a screw gun, neither have the benefits of a screw gun such as set depth or clips.
