Load Tables

Floor-to-Floor Clear Span Table

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

  1. Loads include a 60% load duration increase on the fasteners for wind or earthquake loading
  2. Install bolts or nails as specified by Designer. Bolt and nail values may not be combined.
  3. Allowable bolt loads are based on parallel-to-grain loading and these minimum member thicknesses: MST – 2 1/2"; HST2 and
    HST5 – 4"; HST3 and HST6 – 4 1/2" .
  4. Use half of the required nails in each member being connected to achieve the listed loads.
  5. When installing strap over wood structural panel sheathing, use 2 1/2" long nail minimum.
  6. Tension loads apply for uplift as well when installed vertically.
  7. NAILS: 16d = 0.162" dia. x 3 1/2" long, 16d Sinker = 0.148" dia. x 3 1/4" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.

Load Values with Nails

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

  1. Loads include a 60% load duration increase on the fasteners for wind or earthquake loading
  2. 10dx1 1/2" nails may be substituted where 16d sinkers or 10d are specified at 100% of the table loads except where straps are installed over sheathing.
  3. 10d commons may be substituted where 16d sinkers are specified at 100% of table loads.
  4. 16d sinkers (0.148" dia x 3 1/4" long ) or 10d commons may be substituted where 16d commons are specified at 0.84 of the table loads.
  5. Use half of the nails in each member being connected to achieve the listed loads.
  6. Tension loads apply for uplift when installed vertically.
  7. NAILS: 16d = 0.162" dia. x 3 1/2" long, 16d Sinker = 0.148" dia. x 3 1/4" long, 10d = 0.148" dia. x 3" long,
    10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
