Why is it preferred to use joist hangers instead of toe-nailing?

Using joist hangers is preferred over toe-nailing primarily because they offer better structural support. Joist hangers provide a dedicated and secure method for attaching joists to beams or ledgers, which helps to maintain the integrity and stability of the structure. They distribute loads more evenly and can effectively support the weight of the joists, reducing the risk of failure that might occur with toe-nailing, which relies on angled nails that may not provide as strong a connection.

Joist hangers also allow for precise placement of the joists, ensuring they are level and aligned correctly, which is essential for the overall performance and safety of the construction. This method of attachment contributes to the longevity and durability of the structural components compared to toe-nailing, which can result in weaker connections due to potential movement or shifting over time.
