Standard joist hangers require 1-1/2 nails
When using standard joist hangers, it is recommended to use 1-1/2 inch nails. These are typically used for nailing into the side of the joist. Longer nails that penetrate the wall ledger can offer better load capacity and more protection against uplift forces caused by wind. However, when using standard joist hangers, longer nails may poke through the joist and splay out the other side of the hanger. Therefore, it is important to use the appropriate nail length for the specific joist hanger being used.
The 1-1/2 inch nails are commonly used with joist hangers that have nail holes allowing a nail to be driven perpendicular through the side of the hanger into the joist. This ensures that the nail provides sufficient support and holds the joist securely in place.
It is important to note that the specific nail requirements may vary depending on the manufacturer and the type of joist hanger being used. Some manufacturers, like Simpson and USP, specify the required nail lengths for their products, and it is important to follow their recommendations to ensure safety and structural integrity.
In some cases, shorter nails can be used to fasten the joist hanger directly into the ledger board. However, if short nails are used at the joist, they may not penetrate the ledger board, resulting in reduced support. Therefore, it is crucial to refer to the manufacturer's guidelines or seek professional advice to ensure the proper nail length and type are used for the specific application.

Double shear joist hangers need 10d nails
When it comes to joist hanger nails, it's essential to select the correct type and size to ensure the safety and integrity of your construction project. Double shear joist hangers typically require 10d nails, which are specifically designed for this application.
The 10d nail is a common type of nail used in construction. Its dimensions are standardised, with a shank length of 3 inches and a shank diameter of 0.128 to 0.148 inches, depending on the source. This nail size is specifically chosen to provide the necessary shear strength required to hold the joists securely in place.
While some sources recommend using 1.5-inch nails for joist hangers, it's important to note that these shorter nails may not be suitable for all situations. In some cases, longer nails are necessary to provide adequate support. For example, when driving nails at a 45-degree angle through the joist and into the ledger board, longer nails are needed to ensure they penetrate the ledger board and provide structural support.
Using the correct nail type and size is crucial for the performance and safety of the structure. Nails that are too short or lack sufficient shear strength can compromise the integrity of the construction. It's always recommended to refer to the manufacturer's specifications and industry standards when selecting nails for joist hangers or any other structural application.
When in doubt, it's advisable to consult with a professional or refer to reputable sources for guidance on the appropriate nail type and size for your specific construction project.

Double hangers use 8d or 10d nails
When it comes to joist hanger nails, it is important to use the correct nail length to ensure the structure's integrity and safety. While there are various types and sizes of nails available, the specific nail length for joist hangers can vary depending on the application and local building codes. Double hangers, in particular, typically use 8d or 10d nails, and it is crucial to select the appropriate nail size for adequate support.
The "d" in nail sizes, such as 8d or 10d, represents "penny," a term originating from the Roman coin "denarius" that was also the name for an English penny. So, 8d refers to an 8-penny nail, approximately 2.5 inches long, while 10d denotes a 10-penny nail, usually 3 inches in length. These nails are commonly used in construction and carpentry for joist hangers and other applications.
In the context of double hangers, 8d nails, with a length of 2.5 inches, are often used. These nails provide sufficient holding power for many applications. However, when additional strength or shear resistance is required, 10d nails, measuring 3 inches in length, are the preferred choice. The increased diameter of the 10d nail provides superior holding power, making it better suited for certain projects.
It is worth noting that the specific nail length required for double hangers may vary depending on the project and local building codes. While 8d and 10d nails are commonly used, it is always advisable to refer to the manufacturer's recommendations, project specifications, and local regulations to ensure the correct nail size is selected. Consulting with a professional or referring to building plans can help determine the most suitable nail length for a particular application.

3-1/2 16d nails are for hangers on wall ledgers
When it comes to joist hanger nails, ensuring you have the right size is crucial for effective support and safety. While there are various nail sizes available, the specific length required depends on the type of joist hanger and the application.
For attaching joist hangers to wall ledgers, 3-1/2-inch 16d nails are recommended. This combination provides added strength and stability. The longer nails penetrate the framing members behind the ledger, maximizing their holding power. This is particularly important for outdoor applications, where wind uplift forces must be considered.
It's worth noting that 16d nails are not the most common choice for joist hangers, as they can be challenging to install by hand. Instead, ""teco" nails are often used. These nails are shorter and more manageable, typically used for single two-by ledgers. However, in situations where maximum holding power is required, the longer 16d nails are preferred.
When working outdoors, it is essential to use galvanized or stainless steel nails to resist corrosion. For indoor applications, standard common nails are typically used. Additionally, it is advised to follow the manufacturer's recommendations for the specific joist hanger to ensure optimal performance and safety.
In summary, while various nail sizes can be used for joist hangers, 3-1/2-inch 16d nails are specifically recommended for wall ledgers to achieve superior holding power and strength.

16d sinkers can replace 10d commons
When it comes to joist hanger nails, it is important to use the correct type and size of nails to ensure the structure's safety and integrity. The use of improper nails in joist hangers is a common issue, and it is crucial to follow the manufacturer's specifications and local building codes.
Now, let's address the statement, "16d sinkers can replace 10d commons." This statement is generally true, but it is important to understand the differences between these nails and some important considerations. 16d sinker nails are 3.25 inches long and have a diameter of 0.148 inches. They feature a waffle pattern on the head, which provides a non-skid surface for the hammer and are available with various coatings, such as vinyl, epoxy, and cement. On the other hand, 10d common nails are 3 inches long and have a diameter that may vary slightly depending on the manufacturer.
When substituting 16d sinkers for 10d commons, it is important to note that they have the same shear capacity in most cases, as mentioned by a user on a carpentry forum. Additionally, 16d sinkers are 1/4 inch longer than 10d commons, providing slightly more holding power. However, it is crucial to verify this information with your local building inspector or refer to your house plans, as requirements may vary.
While 16d sinkers can be used in place of 10d commons in certain scenarios, it is not always the case. Some building codes and inspectors may have specific requirements where the use of common nails is mandatory. For example, when framing with 16d commons, pressure-treated mud sills or bottom plates should be attached with HDG 16d common nails. Additionally, when nailing a stud to the top or bottom plate, the latest building codes specify the use of two 16d common nails or three 10d box nails, not sinker nails.
In conclusion, while 16d sinkers can often be used as a substitute for 10d commons in certain applications, it is crucial to consult with local authorities, refer to the specific requirements of your project, and understand the limitations of each type of nail to ensure the safety and compliance of your construction project.
