The gauge of a finish nail is actually a measure of its diameter. The higher the number, the thinner the nail is; the lower the number, the thicker it is.
Finish nailers G16 - 1.6 mm
Our gauge 16 finish nails are slightly larger than a brad nail, giving them increased holding strength. The G16 & G15 finish nails are the most versatile for interior carpentry and also have quite a bit of overlap in terms of application. Both are commonly used for installing baseboard, chair rail, door and window casing, crown molding, door frames, and more.
