Purpose of Joist Hangers

Joist hangers are designed to tightly secure joists, preventing them from warping and twisting over time. By restricting movement and deformation, they ensure the stability and longevity of the structures they support.

Installation Process

Installing joist hangers is a straightforward and cost-effective process. They are typically installed over the sides and edges of beams using galvanized screws and nails. In some cases, they may also be welded for enhanced versatility.

Follow these steps for installation:

  • Align the top plane of the joist with the rim joist.
  • Position the hanger snugly under the joist and temporarily secure it by hammering the prongs into the rim joist.
  • Fasten the rim side first using galvanized nails or screws through all pre-drilled holes.
  • Ensure all holes on both sides of the hanger are filled with nails for a secure fit.

Using the correct fasteners and following these steps helps maintain the integrity of the structural connection.

Weight and Size Considerations

Joist hangers come in various sizes to accommodate different weight capacities:

  • 2 x 12 joist hangers: Minimum 850-pound vertical bearing capacity
  • 2 x 10 joist hanger: Minimum 605-pound capacity
  • 2 x 8 joist hangers: Minimum 540-pound capacity
  • 2 x 6 joist hangers: Minimum 305-pound capacity
