Choosing a Finish Nailer - 16, 18, 21, 23 Which Gauge?
Which finish nailer should I buy? Sometimes this can be a hard one to pin down given the smallest of differences between them. Despite the small differences, one size does not fit all. You will get the best results using the right nailer, whether you're installing doors, crown molding, fine trim, or assembling cabinets. These applications each require a certain size of nail referred to as a gauge. Gauge is essentially the thickness of the nail, however, a higher number means a thinner nail. The most common gauge sizes are 15, 16, 18, and 23 gauge. Let's break them down to gauge what works best for you.
15 and 16 gauge Finish Nailer
So, we start with the 15-gauge finish nailers, and like I mentioned earlier this would be on the thicker side. This is ideal for heavier jobs working with thick, dense wood, door trims, casings, or hanging doors. 15-gauge finish nailers are more powerful, and the nails come with round heads giving you the penetrating power and holding power needed for these types of applications.
- base moldings
- interior trim
Because it's smaller, it has a little less holding power than the 15-gauge and leaves a smaller hole. So, if you're looking for just the right amount of power with a slightly cleaner finish, then our upcoming FN1664 16-gauge finish nailer would be your most versatile.
18 gauge Finish Nailer
- Baseboard shoe molding
- Decorative moldings
- Assembling small DIY projects
Brad nails are thin wire-like nails and because they are so thin they often eliminate the need to fill in holes left behind. However, you will not get the holding power as the 16-gauge but you won't need it if you're using it on the above-mentioned applications. If you're thinking about joining thick pieces of plywood or hardwoods, then a brad nailer won’t have enough power to join these materials properly. If you’re looking to join anything smaller, then EVERWIN’s FN1850 18-Gauge Brad Nailer would be a great choice.
21-gauge Finish Nailer

This size leaves a smaller indent in the workpiece compared to the 18-gauge, but with just enough holding power, excellent for more delicate work. As you go higher in gauge, the indents in the workpiece keep getting smaller which means you might keep on nailing without realizing that the tool had run out of fasteners. To combat this, a useful feature on our models is the dryfire lockout that prevents the tool from firing when there are no fasteners in the chamber.
23 gauge Finish Nailer
For the most delicate and intricate finish work, most pros turn to the 23-gauge. As with its 21-gauge relative, according to the current regulations in North America, they don’t require contact trips. This means that you won’t have that extra element pressing into your precious workpiece, leaving an almost invisible hole. Keep in mind that headless pins have little holding power and are not meant to be structural. 23-gauge pins are normally combined with adhesives to create a more permanent bond.
- To avoid splitting or damaging moldings
- Pinning into corners
- Tacking a hardboard or MDF pattern
If you’re looking for an industrial strength pinner, look no further than our P635B 23-gauge Micro Pinner, a 23-gauge that drives 35mm headless pins without splitting and requires no touch-up work. There is also a 50mm option, the P650 23-gauge Pin Nailer.
