See footnotes below.
- See General Notes for Straps and Ties.
- Install bolts or nails as specified by designer. Bolt and nail values may not be combined.
- Allowable bolt loads are based on parallel-to-grain loading and minimum member thickness: MST — 2 1/2".
- Splitting may be a problem with installations on lumber smaller than 3 1/2"; either fill every nail hole with 0.148" x 1 1/2" nails or fill every other hole with 0.162" x 2 1/2" nails. Reduce the allowable load based on the size and quantity of fasteners used.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
