Question Galvanized vs stainless for mounting Pergola hardware to concrete

Going to be putting in a pergola soon, and am shopping for concrete anchors to attach the footers to the concrete. Is it really worth paying the 100% premium to step up from the galvanized anchors to the stainless ones? I'm in Colorado, so there will be some exposure to the elements. However, I am also going to install these over the hex heads, so they will have a fair amount of protection...

What type of fasteners are you going to use ?

I use lead shields and galvanized lag bolts for some jobs like that.
There are also expansion anchor systems.

I am going to use these. Their stainless counterparts are double the price...

Those are like a TapCon screw. They have their place but in my opinion.... in the ground where they are prone to get wet... is not one of them. I still recommend using lead anchors and galvanized screws.

Great recommendation, thanks. Also glad to know I shouldn’t worry too much about galvanized.
