A34 Framing Angles and Plates Load Table
  1. Allowable loads are for one angle. When angles are installed on each side of the joist, the minimum joist thickness is 3".
  2. Some illustrations show connections that could cause cross-grain tension or bending of the wood during loading if not reinforced sufficiently. In this case, mechanical reinforcement should be considered.
  3. Connectors are required on both sides to achieve F2 loads in both directions.
  4. A34 installed with 0.131" x 1 1/2" nails onto 1 1/4" LSL material will achieve 0.90 of the listed F1 and F2 loads.
  5. Some load values for the stainless-steel connectors shown here are lower than those for the carbon-steel versions. Ongoing test programs have shown this also to be the case with other stainless-steel connectors in the product line that are installed with nails. Visit General Corrosion Risks for updated information. Reference Load Values with Stainless Steel Nails table below.
  6. The allowable loads of stainless-steel connectors match carbon-steel connectors when installed with stainless-steel Strong-Drive® SCNR Ring-Shank Connector nails. For more information, refer to engineering letter L-F-SSNAILS.
  7. Fasteners: Nail dimensions in the table are diameter by length. SD screws are Simpson Strong-Tie® Strong-Drive SD Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
