Need to install a wood post into solid concrete

[Torn Mind]

Whoever built the original fence cut corners, and instead of putting two extra posts and a fence, decided to use the shed itself as one part to hold the gate in and as barrier to entering the patio. The shed also fell over due to wind, as there were scrawny nails and untreated 2x3s as its base.

I need at least one post installed for the gate. The other depends on whether I want to just put the shed back with no fence or whether I want to install a fence first and then rebuild the shed.

This is what I plan to use to hold the post.

But the anchor screws is where I have questions. Is the minimum length of 1/2 inch wide, 2-3/4 in long, good enough to hold an approximately 6 foot fence post?

I'm also leaning towards buying 304 stainless, as Maryland is a state that gets enough precipitation, and it seems that zinc-coated anchors don't offer much rust resistance. Hot-dipped galvanized is better than zinc coated, but I don't know how long before the galvanized layer is worn out. I mean, this is a house that more intended to rent or flip, but I'm not about to sacrifice build quality here. So, stainless or hot-dipped galvanized?

Advice on choice of anchors for holding down the shed base would also be appreciated.

Looks kind of iffy to me. I'd add a brace about half way up the post and anchor the other end about 3 feet from the post. That way if your SO decides to add some heavy planters to the gate (as the are want to do!) or kids swing on the gate you'll be covered. And yes, SS bolts. The upgrade price of SS bolts amortized over the life of the post will be almost zero.

i would probably use 4 wedge anchors in the largest size i could drill the holes in the slab, or epoxy in bolts. I would use hot dipped, but its very dry here and nothing really rusts.

It's not the bolts/mounting I'd worry about, it's the bracket itself that may bend.

Just set the post in concrete with a gravel base.

Those brackets bend, rust and rot the wood. In concrete you just have the rot part to worry about and that won't happen in your lifetime.

What the guy above me said. Just bury the post with either gravel or cement. It'll last longer...
