So, thinking about getting a Max Jax in the future, but am not thrilled about having open anchor bolts collecting dirt in my floor. Has anyone found a plug that fits? I think they are 5/8" bolts, so some kind of plastic or stainless, headless screw that can be left inserted when the unit is in storage? I found 5/8" set screws, but they still have the hex head that will fill up with dirt. I suppose that is better than the whole anchor filling up, but a plastic plug would be even better. Or a plastic or rubber plug to put into the top of the set screw?

You don’t want a plastic plug. Drive a hard caster or something similar and it will break the head off and push the shank down into the hole. I will never repeat that mistake again.


On the super large pallets on the large gantry CNC gantry mill had threaded holes for attaching fixtures or clamps for odd part. We just used hex drive set screws and to clear the chips and coolant from the heads we blew them out with a 4’ air wand with a little plastic shield 10-12” from the end to keep **** from coming back at your face

In our last house I had a Harbor Freight Tire changes bolted to the floor. I'd unbolt it when not in use. To fill the holes I bought cheap bolts at a farm and ranch store (Atwoods if it matters) cut the heads off, sanded the heads smooth and square and cut a slot in the head for a screwdriver. I gave the heads a light shot of Rust preventing paint and screwed them down flush with the floor with a dab of antiseize.

I wonder if you could use a conventional die to cut threads on lengths of nylon rod to make threaded nylon plugs for the anchor holes? Cut a slot in the head and lubricate them before putting them in place.

McMaster Carr has threaded nylon rod in 5/8, so that would be an option. Cut it down, cut a slot across and then all I have to worry about is dust in the slot. And being plastic, would be easy to drill out if it got stuck.

That's probably a good point for garage floors what see a lot of caster traffic, but I don't know how applicable it would be to the typical home garage. I know it wouldn't be a concern in mine.

Tool carts, floor jacks, tablesaws rolled out to be used is pretty common in garages I have been in?

I had one for three years and didn't have plugs... no issues
