  1. Blocking shall be provided beyond headers.
  2. Metal ties not less than 0.058 inch [1.47 mm (16 galvanized gage)] by 11/2 inches (38 mm) wide with eight 16d common nails on each side of the header-joist intersection shall be provided (see Figure 2308.11.3.3). The metal ties shall have a minimum yield of 33,000 psi (227 MPa).
