So I plan on using the Simpson Strong-Tie Model PBS44AZ post base. Further below are picture of what the base looks like.

They recommend installing as follows: Install with 16d common nails, #10 x 1-1/2 in. Strong-Drive SD screws or 1/2 in. diameter machine bolts

I will be using 5 of these with the 5 pressure treated posts that need replacing. The other side of the carport is attached to the house.

I plan on using either Strong-Drive SD screws or 1/2 in. diameter machine bolts. Which would you recommend?

Also do these seem rust resistance enough, I hope they will last 40 years?

  • Your profile says you are located "North East". Is that in the U.S., U.K., Australia, South Africa, etc.? And is the project located in the same place?

Well I found a table to the allowable loads here, and it doesn't seem to matter which way they are fastened as long as it used one of the methods per the instructions. I am going to use the Strong-Drive SD screws as they seem to be the easiest to use.
