HPT Hurricane Tie
Simpson Strong-Tie® introduces a new solution for rafter-to-wall retrofits in Hawaii: the HPT hurricane tie.
The HPT is specially designed and tested for single-wall homes and meets Hawaii state requirements for uplift resistance. The unique design of the HPT connects the wall to the rafter, avoiding interference from the blocking. The strengthened transition area of the HPT helps the structure resist high wind and allows the transfer of forces from the roof to the wall to help prevent damage. The HPTZ features a galvanized coating, while the HPTSS is stainless steel for maximum corrosion resistance.
Finish: ZMAX®, also available in stainless steel; see Corrosion-Resistance.
Features:
- Designed to meet the Hawaii Wind Resistive Devices (WRD) required minimum of 400 lbs. of allowable uplift capacity per the state of Hawaii’s loss mitigation program
- Installs easily with Simpson Strong-Tie® SD screws (one part per connection) OR with 10dx1 1/2 nails (two parts per connection). Either HPT connection requires an additional 1/4 x 1 1/2 Simpson Strong-Tie® Strong Drive® screw (SDS) at the trim board
- The HPTSS must be used in pairs and only with stainless-steel nails
Some products may be installed with the Strong-Drive® SD Structural Connector screw -

These models are approved for installation with the Strong-Drive SD Structural-Connector screw.See the load values.
- Loads have been increased 60% for earthquake or wind load, with no further increase allowed; reduce where other loads govern.
- In the nailed application, two HPTZ or HPTSS must be used as shown above to achieve the minimum of 400 lbs required by the State of Hawaii.
- Parts are only shipped in equal quantities of lefts and rights. (right shown above)
- A Strong-Drive® screw is required at each connection to fasten the trim board to the wall board to transfer load to the exterior sheathing.
- Maximum trim board thickness for these installations is 3/4". For greater thickness use longer Strong-Drive screws, available in 2", 2 1/2" and 3" lengths.
