My shop had at least two heavy equipment lifts in it before I bought it. I flush cut all the anchor studs but left a group in place in one bay. Where should I look for a anchor plate for a winch/come a long?

Its probably an oddball bolt pattern. Best bet will probably be to have a welding shop make one up for you. A 4wd / truck shop might have one that you can drill for your own bolt pattern.

I made one.

Put the right size washer over the studs, then measure the OD of the washers. That’s the plate size.

For the one I made, I took my torch and heated up a piece of rebar and bent it into a loop and welded on to the plate.

Not sure what you are using it for, but I used epoxy to anchor a galvanized Machinery Eye Bolt 1/2” at the back of garage for pulling immobile cars back into the garage

Make a template to match the bolt pattern, just like when you make a paper gasket by tapping lightly with a ball peen hammer; and have a fabricator build you a suitable anchor; maybe with a Pad Eye in it.

I did the same. I think I used them twice since I built the place in 2003.

One is now under a workbench along the back wall, and not very accessible.

The other is a trip hazard.

if I was doing it again, I would use a flush threaded insert.

You can also use a chain pot, but most people are probably going to deem it more work to core drill for the chain pot than it is to make a plate.


When I built my shop, my intent was to set the chain pots when the floor was poured. It didn’t happen for various reasons. But if anyone is ever pouring a new floor, chain pots may be an option for you. They’re still an option after the floor is poured, but you have to core drill.

Another option for flush mount is to get a 1” coupling nut and epoxy that in the floor. When you want to pull something, thread the eyebolt in, when you’re done remove the eyebolt and push in a plastic cap to keep the dirt out.

Chain pots ****.
They **** in a bodyshop where they have an actual day to day use, they **** more if you have a general purpose workspace with infrequent use.

To the OP if you must keep the anchors (and I wouldn't - see below)
Take a piece of cardboard - tap on stud locations.
Transfer pattern to a piece of ~1/4" plate.
Weld on 2 D-rings 90degrees from each other.

If you want to have an anchor point that is for occasional use - use a female insert and put a plug in it or sink it a bit and install a countersunk cap screw to keep stuff out of the threads.

That would work, floor studs are 12' inside shop door. If I wanted to pull evenly I'd need to use both sets i.e. (2) groups of (4) studs that are 8' apart.

To each their own, I suppose. Personally, I love chain pots. Day to day and occasional use both.
