When you want to fasten trim or join two small pieces of wood and do it without leaving large, unsightly nail holes, the pin nailer is always the best tool to turn to.

With the best pin nailer, working with smaller and more delicate material is much easier as you can easily join the pieces without splitting or leaving large nail holes.

These nailers shoot 23-gauge headless or slightly headed fasteners which explains why they do not leave large holes and most will use fasteners that are between 1/2 and 1-3/8 inches long.

And if you are on the market for one, this piece is for you as we make it easier for you to choose a good model by reviewing 7 top-rated pin nailers and with an in-depth buying guide.

What To Check Before Buying Best Pin Nailers?

Picking the best 23-gauge pin nailer from the many options is not rocket science as you only need to consider the following things.

1. Pneumatic vs. Electric Pin Nailers

The power source will determine how powerful and efficient the pin nailer will be, and it will also affect other things like the cost. You will typically need to choose between the pneumatic and electric pin nailer when shopping

Pneumatic Pin Nailers

Pneumatic pin nailers are powered by an air compressor which means you need to buy one if you do not already have it for powering other power tools.

They are generally more powerful than most electric types, and this explains why they are the preferred option for professional woodworkers. And besides the cost of buying an air compressor, pneumatic pin nailers are relatively more affordable.

However, with these nailers, the cost of operation is relatively higher and they are also not very portable as you have to drag the air compressor along with you.

Electric Pin Nailers

Electric pin nailers run on a motor that can either be battery-powered or plugged in depending on the type. And they are highly convenient nailers that are very popular with hobbyists and DIYers.

These pin nailers offer the convenience of not having to buy or use an air compressor, and this also makes them relatively more portable despite being relatively heavier than the pneumatic pin nailers.

The only significant shortcoming with the electric pin nailers is that they are relatively pricier when compared to the pneumatic types, but the good news is that they have a lower operation cost.

2. Nail Size

The nail size that the pin nailer uses will determine the applications you can use it for, and so it is also an important factor to consider when shopping.

A pin nailer that shoots nails that are between 1/2 and 1-inch long like Freeman PP123 should be good enough but those that can accommodate 3/8 to 2-inch long nails are more preferable.

The projects you intend to use the pin nailer for should guide you when determining the nail size you need. Generally, short pins are ideal for softwoods while longer ones are what you need for hardwoods.

3. Depth Adjustment

Given that you will probably be dealing with different material sizes and thicknesses, a good pin nailer is one that allows for depth adjustment to suit different materials.

With depth adjustment capability you can easily determine how deep you sink the pins and hence the amount of hold power you get.

But, besides having depth adjustment, the pin nailer should make the depth control easy and those with a simple tool-less depth control knob or wheel are the best choice.

4. Magazine Capacity

Magazine capacity might not be important to those that only have to fire a few pins to hold two pieces together as the glue dries and do it occasionally. But, for woodworkers that use their pin nailer regularly the magazine capacity matters.

The magazine capacity or the number of nails the pin nailer can hold will determine how much you can do before you have to reload.

A larger magazine is always the best as it will reduce the reloading frequency which minimizes downtimes and increases productivity.

And while the right magazine capacity for you will depend on how you use your pin nailer, something that can hold at least 100 fasteners like the Bostitch HP118K is often good enough.

5. Extra Features

Many pin nailer manufacturers will always give their tools a few extra features to make them more efficient and convenient for the user.

Some of these extra features to look out for is tool-free jam clearing as it will help minimize downtimes, dry fire lock-out mechanism to prevent dry fire damages and a dual trigger safety lock to prevent accidental firing.

Also, a pin nailer that comes with a no-mar tip to protect the workpiece from dents and scratches, rear exhaust system, safety glasses, and a carry case will make a good buy.

Pin Nailer vs. Brad Nailer

Pin Nailer 

Pin nailers are designed to shoot some of the thinnest fasteners among all finish carpentry nailers. These fasteners are typically 23-gauge and will either be completely headless or slight headed.

The thinner gauge and lack of a head mean that these nailers will not leave any visible nail holes like the 18-gauge brad nailers. Also, these fasteners will hardly ever split wood even when dealing with delicate trim and thinner pieces of wood.

But, the small size of the fasteners means that they will not provide a lot of hold power, and so many woodworkers will prefer to use them to hold two pieces of wood as the glue sets as they are also easy to pull out.


  • Does not leave visible nail holes
  • Will not split wood
  • Great for keeping wood together as the glue dries


  • Not much holding power
  • Limited applications

Brad Nailer

The brad nailers shoot 18-gauge fasteners which are larger than the 23-gauge pin shot by a pin nailer and this means they provide more hold power.

While the holding power might not be as much as what you get from other nailers such as the 15-gauge, it is still enough to make the brad nailer one of the most popularly used finish nailers.

Brad nailers are ideal for various applications such as base-boarding, trim work cabinetry, and crown molding. However, the larger fasteners with flat heads that they shoot are more likely to split delicate pieces and will leave larger nails holes that often require filling.


  • Relatively more hold power
  • More versatile and ideal for various applications
  • Great for base-boarding


  • Can easily split delicate pieces
  • Leaves relatively larger nail holes

Buying Advice: Both pin and brad nailers will be very useful to have around, and if you can afford both the better. However, if you are looking for something more versatile and with more hold power, go for the brad nailer. But, if you want a nailer that will not split your delicate pieces and does not leave noticeable nail holes that require filling, the pin nailer is your best bet.


Pin nailers are highly useful power tools for those that deal with delicate trim and wood pieces or want something to keep wood pieces together as the glue dries.

From this review, the Hitachi NP35A is the stand-out and best overall product as it has the power, versatility, features and also comes at a fair price tag.
