Fastener choice is one of the most common mistakes with many connectors, but especially with joist hangers.

  • The required fastener type is usually stamped on the connector. Do not substitute. Using a nail with a different diameter, length, or steel type can reduce shear capacity.
  • When using screws, use only those specified by the manufacturer. Do not use deck or other screws: They are too brittle.
  • For connectors that require the use of bolts, drill a hole no more than 1/16 in. diameter wider than the bolt. Larger holes will compromise the strength of the wood.
