  3. Allowable bolt loads are based on parallel-to-grain loading and minimum member thickness: MST — 2 1/2".
  4. 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.
