When it comes to size, nail guns have a wide selection. The measurements typically range from 16-gauge through 20-gauge. The gauge assigned to each gun is actually linked to the diameter of the nails it can handle, with a lower number denoting a thick nail.
Nail thickness varies drastically depending on the intended use. 16-gauge nails are the sturdiest and are often employed for heavier projects such as framing. 18-gauge nails are a bit thinner and widely used for jobs like trim work. The thinnest of the bunch, 20-gauge nails, are indispensable for detailed projects such as installing crown molding.
Nail guns come in a few different sizes, but the most prevalent are the three mentioned. When selecting a nail gun, size and type of nail must always be thoughtfully assessed. An incorrect size nail gun could end up leading to material harm or even physical injury, so being aware of the details is key!
