Nail guns are available in a variety of angles, ranging from 15 to 34 degrees. The degree of a nail gun refers to the angle of the magazine, which holds the nails, and the nail collation, which is the way the nails are held together. The angle does not refer to the angle at which the nails are driven, as all nails are driven straight into the surface. The degree of a nail gun can impact its ability to access tight spaces and the number of nails it can hold. Additionally, the type of nail head and local building codes may also influence the choice of nail gun angle.

What You'll Learn

The degree refers to the nail collation and the magazine angle
The degree of a nail gun refers to the nail collation and the magazine angle. Framing nail guns have different angles, which range from 15 to 34 degrees. The angle does not refer to the angle at which the nail is driven, as nails are always driven straight and perpendicular to the surface. Instead, the degree of a nail gun refers to the angle of the magazine, which is attached to the head of the gun and angled away from it.
The two main types of framing nail collation are stick and coil collation. Stick collation refers to nails that are held together with paper or plastic and come in a long, straight strip. Coil collation, on the other hand, refers to nails that are wire-bound with two thin wire strips and come in a circular shape. While stick collation is often used for nails with a full-round head, coil collation is commonly used for nails with a clipped head.
The degree of a nail gun also determines the type of nail collation and the number of nails that can be held in the magazine. For example, 15-degree nail guns use wire coil collation and can hold a few hundred nails, while 21-degree nail guns use plastic collation and typically hold around 60 nails. 30-degree nail guns use paper collation, which allows for more nails to be held in the magazine, but may malfunction in wet conditions.
The choice of nail gun degree depends on various factors, such as the type of nail head and local building codes, as well as the specific requirements of the project, including the need to work in tight spaces. It is important to consider the advantages and disadvantages of each nail gun degree and select the one that best suits the specific application and local regulations.

15-degree nail guns are ideal for floor joists and corner framing
The angle on a nail gun refers to the nail collation and the angle of the magazine, not the angle at which the nail is driven. Nails are always driven straight or perpendicular to the surface. The angle of the nail gun is important because it determines the tool's range of motion and how efficiently it can work in tight spaces.
The 15-degree nail gun is ideal for floor joists and corner framing. This is because the 15-degree nail gun can hold a large number of full-round-head nails, which are often required for framing by building codes. The full-round-head nail is the preferred head shape for building code. The collation of the 15-degree nail gun is circular in shape, and the nails are held together by two thin wire strips. This type of collation is beneficial because it is not as harshly affected by moisture as paper collation.
The 15-degree nail gun is also advantageous because of the amount of fasteners the magazine can hold. For example, the Metabo HPT (formerly Hitachi) NV83A5M holds 200-300 nails, which means less stopping to reload during a project. This is especially useful for extended work and for projects that involve a large number of joists and wall studs.
However, it is important to note that the 15-degree nail gun can be heavy, making overhead work difficult. Additionally, the angle of the nail gun is not adjustable, so a 15-degree angle cannot expand to a larger size.

21-degree nail guns are great for working in tight spaces
When it comes to nail guns, the degree refers to the nail collation angle—the angle of the magazine that holds the nails, not the angle at which the nails are driven. Nails are always driven straight or perpendicularly into a surface. The collation angle determines the type of nail head and the number of nails the nail gun can accommodate.
The 21-degree nail gun is a popular framing nailer angle. It can accommodate full-round-head nails, which are more secure than clipped nails. The 21-degree nail guns are held together in plastic clips that shatter as the nails are driven, leaving small pieces of debris in the work area. This type of nail gun ejects pieces of plastic at high speed, so it is recommended to wear safety glasses while using it. The 21-degree nail guns hold fewer nails than the 15-degree nail guns, making them lighter and more portable. The lower capacity per clip is a trade-off for the light weight and ease of use in tight spaces.
The larger the angle of the nail gun, the more manoeuvrable it is, and the easier it is to fit into tight corners and spaces. While the 30-degree and 34-degree nail guns provide the maximum amount of manoeuvrability, the 21-degree nail gun is still a great option for working in tight spaces. The choice of angle depends on the user's preference and the type of project. For example, the 30-degree and 34-degree nail guns are bulkier and require more upper body strength for a full day's work.
It is important to note that the nail gun angles are not adjustable, and each angle uses its own size of nail and magazine type. Therefore, it is critical to buy nails that match the angle of the nailer. Additionally, the choice of nail gun angle may depend on the geographic location and local building codes, as some areas may require specific types of nail heads or collation for safety reasons.

28-degree nail guns are the only type that can use both nail-head types
The angle on a nail gun refers to the nail collation and, more specifically, the angle of the magazine that holds the nails, not the angle at which the nail is driven. Nails are always driven straight or perpendicular to the surface. The angle of the nail gun can affect the number of nails that can be held in the magazine, the weight of the nail gun, and the ease of accessing tight corners.
Nail guns typically have angles ranging from 15 to 34 degrees. The 15-degree nail gun is ideal for floor joists and corner framing and can hold a few hundred nails, reducing the need to reload during a project. The 21-degree nail gun can also accommodate full-round-head nails but holds fewer nails than the 15-degree nail gun. The greater angle, however, gives better access to tight corners. The 30-degree nail gun provides the best access to tight corners and uses offset-head or clipped-head nails. Its magazines often hold two strips of nails, reducing the need for frequent reloading.
Among all the nail guns, the 28-degree nail gun is unique in that it can accommodate both full-round-head and clipped-head nails. To save magazine space, the nails are "nested" closely together, with their heads overlapping. This design makes the 28-degree nail gun a more compact tool compared to other angled nail guns. However, it is important to note that not all building codes allow the use of offset-head or clipped-head nails in framing jobs due to safety concerns. Therefore, it is crucial to research local area building codes before choosing a nail gun to ensure compliance with the regulations.
When choosing a nail gun, it is essential to consider the specific requirements of your project, the geographic location, and the applicable building codes. The best choice is the one that suits your needs and provides the most comfort and ease of use for the task at hand.

Local building codes may limit your nail gun options
The angle degree on a nail gun refers to the nail collation and the angle of the magazine, not the slant that the nail is driven into. The nail collation is the way in which the nails are held together. The angle of the magazine is the angle at which the magazine holding the nails is attached to the head of the gun. Nail guns come in a variety of angles, from 15 to 34 degrees. The angle of the magazine determines the type of nail that can be used with the gun. For example, a 15-degree nail gun uses nails held together by two thin wire strips, while a 21-degree nail gun uses nails held together by plastic clips.
The 15-degree nail gun is ideal for floor joists and corner framing as it can access tight spaces. It also holds more nails, reducing the need to reload during a project. The 21-degree nail gun is also useful for tight spaces, but it has a lower capacity per clip, leading to more frequent reloads. The 28-degree nail gun has a larger capacity and can hold two full strips of nails. However, it is heavier, requiring more upper body strength. The 30- and 34-degree nail guns are the most common on construction sites as they offer the most advantage in tight spaces. Nevertheless, they are the heaviest options.
Ultimately, the right nail gun for your project will depend on various factors, including local building codes, the specific tasks you need to perform, and your personal preferences. It is important to consider the trade-offs between factors like capacity, weight, and range of motion to choose the most suitable nail gun.
