I am looking for a concrete anchor, that has a removable bolt, to mount my tire changer, then remove it for storage, then cover the holes when not in use.

I like the Red head anchors. Very simple.

I've used the lead anchors when I wanted the lag bolts to be removable. Sinking them down enough to put in something to cover the hole works; if they're out for a while and things get messy in the shop, it may take some doing to clean the holes enough to replace the lags.
These anchors (and the lag screws) are not super-strong; I would not use them for life-critical fastening.

Depending on how many times you install them and take them out, a screw anchor may be your best bet.
We use the Hilti brand and install them by the tens of thousands each year installing industrial pallet rack and mezzanines in large distribution centers. Don't pay attention to the pricing on the snipit below. Obviously, that's not correct.

Same application. Got some SS anchors and some nice SS cap screws to cover when not in use, 1/2-13 size. Got regular longer bolts to go through the changer base to mount when in use.

We used dropins. Drill a hole the right depth, a setting tool is used to hammer the expander tight, then use a bolt in the anchor. Take a bolt in or out as many times as you wish. Good for inside a building cause you can patch/fill the hole and put flooring down.

Can you give a link for those? They look real handy for use in wet areas around the brewery!Same application. Got some SS anchors and some nice SS cap screws to cover when not in use, 1/2-13 size. Got regular longer bolts to go through the changer base to mount when in use.

you'll also need a setting tool for the anchors:

Thanks! Bookmarked.
Most of the stuff I anchor at the brewery is pretty much permanent. I use SS all-thread, sunk the full depth of the concrete floor and anchored with epoxy mastic, but we do have some equipment that needs to be anchored and needs to move occasionally. Those SS drop-ins will be just the ticket. I think SS Allen grub screws will be better for a plug for us, as they can sit flush with the floor.

McMasterCarr sells them and I'm sure many others besides Ebay. And you don't need to get stainless steel unless stainless is really needed.

Yep. $5.45 each in 18-8 SS. Ebay is $26.24 for five. Pretty much a wash, except Ebay is Free Shipping. McMaster Carr is definitely NOT.

Stainless steel bolt inside of stainless steel anchor can be bad news if they decide to gall together... even with anti-seize.

Sometimes you have no choice. Using different alloys of SS for the different parts sometimes helps, but I usually get away with anti-seize.
Lots of things around the brewery use 304 or 316 SS and fasteners of the same. Anti-seize has saves my *** many times on stuff that gets regular maintenance, like butterfly valves.
I have a couple of pieces of equipment in my garage that I don’t want mounted to the floor at all times. I used the drop in anchors as shown above and set them a bit below the surface. I then chamford the whole a little bit and put flat head screws to keep debris from entering the anchors when not in use. Since I am using flat head screws, there’s no chance of any material catching on them or becoming a tripping hazard.

I made my own.
Broke through the floor making a w
2"-3" hole. Remove debris. 3/8" coupling nut with a 4"-6" bolt and washer threaded 1/2 way. Install head an washer down in the hole. Cover the opposite end with tape. Fill with anchoring cement.
I use it the a forged lifting eye to drag things into the garage.
