In structural plans, toe nailing refers to a technique used to connect framing lumber. The required nail size for toenailing depends on the application, location, type of connection, and size of lumber involved. For example, when connecting a wall stud to a sole plate, one can use either three 16d nails or four 8d nails. Here, 3-16d refers to using three 16d nails, which are stronger than 8d nails due to their greater diameter. However, 16d nails are harder to find and may be too large for some applications, potentially splitting the lumber.

What You'll Learn
Toenailing is an unsafe structure that can collapse
Toenailing is a technique used in woodworking and construction to join two pieces of wood together. It involves driving nails at an angle through the side of one piece of wood and into another, creating a strong joint that can resist movement in every direction. While toenailing can be an effective method for attaching wall studs to sole plates, rafters to top plates, and deck joists to ledger boards, it is important to consider the safety risks associated with this technique.
Toenailing, when not executed properly, can lead to an unsafe structure that may collapse. The key to ensuring the safety of a toenail joint is to use the correct number of nails and the appropriate nail size for the specific application, location, type of connection, and lumber size. Using too few nails in a framing lumber connection will result in a weak structure that is prone to collapse. On the other hand, using too many nails can also be detrimental, as it can cause the wood to fracture, leading to a weak connection that can potentially result in structural collapse.
To determine the correct number of nails for toenailing, it is essential to refer to the applicable building codes and nail schedules, such as the UBC Table 25-Q Nailing Schedule. For example, when joining a 2x4 stud, four nails are typically used, with two nails per side, opposite each other, and crossing into the nailed-to member. For a 2x6 stud, six nails are commonly used, with three or four nails per side. It is also crucial to select the appropriate nail size to achieve the required penetration into the nailed-to member. For instance, when making structural connections with larger lumber sizes, the Uniform Building Code (UBC) mandates the use of 16d (3 1/2") common nails with a penetration of 1 3/4" into the nailed-to member.
In addition to using the correct number and size of nails, proper maintenance of toenailed joints is vital for the long-term stability and safety of the structure. Regular inspections for looseness or separation, especially in areas subject to vibration or movement, are essential. If a toenailed joint becomes loose, it can often be reinforced by adding additional nails, using longer nails, or installing a metal bracket without disassembling the structure.
While toenailing can provide strong and durable joints, it is important to be cautious and follow the appropriate techniques and safety measures. Improper toenailing can lead to unsafe structures that may collapse, posing a significant risk to anyone in or around the building. Therefore, it is crucial to prioritize safety and consult applicable building codes and professional guidance when employing toenailing in construction projects.

3-16d nails are large and tough to hammer by hand
3-1/2" 16d nails are large and challenging to hammer by hand. They are hand-driven nails specified for Simpson connectors. Many people mistakenly believe they are collated nails, but they are individual nails sold by the box. There is no gun that can shoot them. According to the Simpson manual, these nails differ in diameter from other types of nails.
The required nail size for toenailing or slant-nailing depends on the application, location, type of connection, and size of lumber involved. For example, when connecting a wall stud to the sole plate, two end-driven 16d nails are typically used. However, a 3-1/2" common nail or 16d might be too large for toenailing and could split the wood, especially if nailed near the edges.
The penny system refers to nail length, with each higher number representing a 1/4-inch length increase in the nail. So, a 16d nail is longer than an 8d nail. The "d" in 16d stands for "penny," which is a unit of measurement for nail length. The nail's length is crucial for providing strength to the structure.
The size of the nail also affects the number of nails required for a secure connection. For instance, while connecting a wall stud to the sole plate, two 16d nails can be used, or four 8d toenails can be used to achieve the same result. Using too few toenails in a framing lumber connection can result in a weak structure that may collapse. Therefore, it is essential to follow the applicable building codes and nail schedules for the specific project.
The large size of 3-16d nails makes them challenging to drive by hand, and they may require the use of a hammer drill or impact driver. Additionally, the increased length and thickness of these nails can make them more difficult to find in standard hardware stores compared to smaller nails.

16d nails are hard to find
16d nails are specified for Simpson connectors. They are hand-driven nails with a 3.5-inch shank length and a 0.162-inch diameter. Many people mistakenly believe they are collated nails, but they are individual nails sold by the box. There is no gun that can shoot them.
16d nails are required to attach studs to plates when building walls. However, they can be challenging to find in hardware stores like Lowes and Home Depot, and they can be expensive to purchase on Amazon. This is surprising, given that they are required by code.
One reason for the difficulty in finding 16d nails may be that some engineers specify the diameter of the nail on their plans, and pneumatic 16d nails have a smaller diameter than non-pneumatic ones. Pneumatic nails are used with a nail gun, which increases driving speed and efficiency. However, not all engineers are aware of this distinction, and some framers may use a pneumatic nail with a reduced capacity.
To find 16d nails, it is recommended to try a building supplier rather than a general hardware store. Additionally, it is important to pay attention to the diameter specifications on the plans to ensure the correct type of 16d nail is purchased.

16d nails are used for non-shearwall/diaphragm connections
16d nails are a type of common nail used in construction. The "d" in 16d stands for "pennyweight", a unit of measurement that indicates nail size. A 16d nail is 3.5 inches long and has a shank diameter of 0.162 inches, although some sources give the shank diameter as 0.135 inches. These nails are large and difficult to nail by hand, so they are typically used with a nail gun. However, most nail guns do not support 16d nails, so an equivalent nail size, such as a 12d or 10d nail, is often used instead.
In structural plans, 16d nails are commonly used for non-shear wall and non-diaphragm connections. Shear walls are structural components that resist lateral forces, such as those caused by wind or earthquakes, and transfer them safely to the ground through the building's structure. Diaphragms are horizontal structural elements that transmit lateral forces to the shear walls. While 16d nails are not typically used for these critical structural connections, they are still an important type of fastener used in construction.
The use of 16d nails in non-shear wall and non-diaphragm connections is specified by various building codes and standards. For example, the International Residential Code (IRC) requires 16d nails for most non-shear wall and non-diaphragm connections. Additionally, the American Wood Council's National Design Specification for Wood Construction (NDS) provides guidelines for the use of 16d nails in these types of connections.
It's important to note that the required nail size for non-shear wall and non-diaphragm connections can vary depending on the specific application, location, and size of the lumber involved. For example, when connecting a wall stud to a sole plate, two 16d nails are typically used. However, in some cases, four 8d toenails may be used instead. As such, it is crucial to refer to the applicable building codes and standards for the specific requirements in a given jurisdiction.

16d nails are used for structural support
16d nails are commonly used for structural support in construction projects. The "d" in 16d stands for penny, which is a standard unit of measurement for nails. Each higher number represents a 1/4-inch length increase in the nail. So, a 16d nail is longer than an 8d nail.
In terms of specifications, a 16d nail typically has a 10- or 8-gauge shank, a 0.135- or 0.165-inch shank diameter, and a 3.5-inch shank length. The head diameter is approximately 11/32 inches. These nails are huge and tough to nail by hand, so they are often used with nail guns.
When it comes to structural support, 16d nails are often used for non-shearwall/diaphragm connections. They are also commonly used for framing and other structural work, especially with 2x dimensional lumber, such as two-by-fours. However, they may be over-sized for toe-nailing and could split the 2x, especially if nailed near the edges of the lumber. In such cases, framing connectors or joist hangers are recommended as an alternative.
The required nail size for toenailing depends on the application, location, type of connection, and size of lumber involved. For example, when connecting a wall stud to the sole plate, two end-driven 16d nails are typically used. On the other hand, when nailing 2x studs to a bottom or top plate, the Uniform Building Code (UBC) requires four 8d common nails, two per side of the stud.
