I used these to strengthen some of my floor joists' ability to resist lateral forces involved in a seismic retrofit. These fit the bill nicely, but be sure to purchase the appropriate hardware including either simpson strong-tie timber hex screws or threaded bolt along with washers/nut. Go galvanized for corrosion prevention if there is any doubt about moisture.

Note that the DTT1 is for tying back into the house, and as such has a 3/8 hole. Use the DTT2 for deck posts - it has a 1/2 hole.

  • Incorrect hole size?
  • July 19, 2016

These have a 3/8" hole for a bolt, yet railing posts require a 1/2" bolt. So i had to drill mine out. I thought these were intended for railing post tie backs...

I ordered this product online - it is a good product but i could not use it as specified. I did not have a header board to screw into. Just used couple of these. I had to use the DTT2Z-K2 kit , which is heavier duty so i could install it into the basement joists. It worked out well. Simpson products are very good with excellent instructions.

This piece is significantly less expensive than all of its counterparts. It is not as robust, but it does the job. I had a cupped 2 x 10 on the outside of my deck and that was the only way to pull it back to the other joists. If I had to use the other ties that were more substantial, I would have been better off changing out the boards. The tie holds a 3/8" bolt, so it is not rated for as much weight. Never found a rating. Perfect for what I used it for.

Pros Easy to Install, Easy to Work With, Economical, Great Value

Easy to install. Had to opt for the 8” lag bolts from Simpson.

Excellent product. Was able to attach kitchen soffit to rafters (this was missed when house was originally built) using these Strong-Ties without doing any reconstruction. They worked well with easy installation.
