Table
  1. Loads have been increased 60% for earthquake or wind loading; no further increase allowed; reduce where other loads govern.
  2. Twist straps do not have to be wrapped over the truss to achieve the allowable load.
  3. Minimum edge distance for Titen screw is 1 1/2".
  4. See Simpson Strong-Tie Anchor Systems® website for full Titen® Screw details.
  5. Table allowable loads were determined using test ultimate/3 or fastener calculation values.
  6. Products shall be installed such that the Titen® screws are not exposed to the weather.
  7. Minimum f'm = 1500 psi and f'c = 2500 psi.
  8. Lateral loads apply when on the wall side Titen screws are installed into the first four hexagonal holes from the bend line and on the truss/rafter the first seven nail holes near the bend line are filled. Any other fasteners required can be installed in any open hole.
  9. NAILS: 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
