The Simpson Strong-Tie DTT tension ties are safe, cost-effective connectors designed to meet or exceed code requirements for deck construction. These versatile DTT connectors are also load rated as a holdown for light-duty shearwalls and braced wall panel applications. Also available in a Deck Tension Tie Kit (which includes all required fasteners), the Strong-Tie DTT1Z deck tension tie features a G185 ZMAX galvanized finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.

  • Use all specified fasteners (see the full DTT1Z Deck Tension Tie Kit).
  • A standard cut washer (included) must be installed between the nut and the seat.
  • Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws install best with a low speed high torque drill with a 3/8" hex head driver.
  • Strong-Drive SD Connector screws install with a 1/4" hex head driver.
  • Strong-Drive SDWH Timber-Hex HDG screws install with a 3/8" hex head driver.

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values

Worked for me

I used these to bring my deck up to code (4 tie-points to the house in addition to the ledger board), and I also used them to reinforce the handrail guard posts. It is strange that Simpson makes two different ties (DTTZ1 and DTTZ2). The DTTZ1 is much cheaper and seems to work just as well. Glad to get my deck sturdy again!
