Deck Post footings/Mudsill anchor???

I had a contractor pour some footings and anchors for me to build a deck this upcoming weekend. They installed Mudsill anchors made by Simpsons like the ones found here:

Simpson Strong-Tie ZMAX Galvanized 18-Gauge Mudsill Anchor-MAB15Z at The Home Depot

The posts are 6x6. Will these work for a vertical post? Just wanted to get thoughts.....

They like they are are made to anchor a horizontal plate/mudsill and not for anything that is vertical. I don't think they would really good for posts if you want real stability.

Simpson does offer a number of fixtures for columns or posts. Take back what you have unless you have another use for them. I think simpsom has a wide range of connector plate to use with either 4x4 or 6x6 and some allow you to have an air gap between the wood and concrete.

Mudsill anchors are not approved for post supports. Why would he install such knowing a deck was to be installed??? You need Simpson Strongtie ABU66 post base, which is a retrofit unit. You can cut off the mudsill anchor at concrete level and drill a 1/2" hole beside it to accept your fastener. Larger hole for lag shields, etc.
