I have to take out a lot of quite old coach screws. Is they any
process of easing them. Like applying WD40 to a bolt.

Just into wood? If so, no special treatment should be required.

If you mean coachbolts, as in screwed into wood - then WD40 etc. will
not help, it will not penetrate far and will be absorbed by the wood at
the surface. Try applying heat to the heat and allowing it to cool,
with perhaps a good thump on the head (of the bolt) with a hammer.

If you mean normal threaded bolts for metal, the WD40 will help. Even
better would be Plusgas or heat.

He could mean coach screws as screwed into wood

or coach bolts which are not screwed into wood but bolted through

If screws then hex socket should work fine without any easing as if they are
quite old there is often some deterioration of the wood around them. Failing
that a single hex impact socket would grip the faces rather than the corners

However if they are old coach bolts which may spin rather than undoing
Then as the heads are a bugger to grip I usually use a cutting disc to
remove the nut and tap the bolt out with a punch

==================================
If they are coach *screws* (i.e. screwed directly into wood) and if
they're old then they will probably have square heads in which case a
close fitting open-ended spanner will be needed. An old machine spanner is
best if one is available.

I doubt if anything can be used to help undoing except steady pressure
with the spanner, but be prepared for some breakages.

Always tighten the screw first,this loosens the grip and allows a much
easier extraction,this applies to bolts as well
