Hi all

We have a treadmill and trying to move into another room but it's too big to fit through door and the heads have gone on bolts to unscrew anything. Any thoughts on what can we do?

Thanks all

Use a dremel or similar to cut a slot in them then use a decent fitting flat blade screwdriver

I often see people recommend using a dremel. I don't own one.

How long does it take to cut the slot? And how do you make it wide enough to accept the screw driver?

They are like a miniature grinder, into which you can fit a thin cutting disc, around 1" diameter. You can cut a slot, then widen the slot out to accept a screwdriver blade. It only takes a few seconds.

Cheers, I have access to one. I guess I need to try it.
 
If they are Allen headed bolts, you might still get the Allen key to fit.
 
It would be useful to know what the bolts are going into. i.e. what is on the other side?
 
A pair of mole grips may be able to grip onto them in order to undo them.
 
If they are allen sockets then they're likely metric: you might find an imperial set will have some fractionally bigger which will grip.

Other options: hex bit in an impact driver, cut a slot with a hacksaw or a slitting disc in an angle grinder to match a straight blade, try the rubber band trick etc.

A lot depends on what tools you have to hand
