Help! What are these...

Could a temporary roof support or acrow prop have been secured with bolts while walls were being re-configured.

Begs the question why they weren't removed?

An angle grinder will reduce the height of the bolt heads IF they cannot be removed ,this will make the fridge freezer levelling up easier .

I would suggest WD40 and a decent torque wrench and socket before invoking the permit to work system and the hassle of appointing a fire marshal.

If you ever come over here and use my torque wrench for undoing bolts, be assured you will quickly find it being inserted somewhere rather uncomfortable. If that doesn't work, there is a 2x4 clue bat in the other toolbox.

Torque wrenches are only ever used to tighten up a bolt to the specified setting.

It's exactly the same the other side, so it looks like it's one plate that goes under the skirting/wall. 

If they disappear under the wall and you can't see all 4 edges of the 'plate' then my guess is they could be bodged-up angle brackets being used to secure the wall to the floor.  I.e. larger versions of this... https://www.toolstation.com/adjustable-angle-bracket/p87232   ...with only one leg being visible.

I definitely wouldn't undo the 'bolts' (possibly coach screws?), or weaken them by grinding the heads, at least not until I knew what they are actually holding up (or down).  The worst case is the metal could be some kind of bodged splice plate holding two structural members together, in which case removing or weakening the fasteners could result in a sudden failure.

I forgot the 'what next' bit....

I'd do a quick electrical continuity (or resistance) test between the two sides.

That won't be proof of anything, but if there is no electrical continuity then you would know it is two pieces of metal not one, and therefore the angle bracket theory might be more likely.

(If there is continuity it means either one piece, or two that are electrically connected, e.g. via bolts or screws touching both pieces)

Then it would be a case of taking the adjacent skirting off to see if anything more is then visible.

Looks like a base plate to a steel column that is built into the wall.  Probably put in to strengthen the wall when some internal walls were removed.

If torque wrenches are only meant to be used for tightening bolts why do they have a switch for reversing direction
