I'd say resist the impulse. The pressure bar exists to supply 
a counter bearing angle at what amounts to the V bar in a 
vertical. If the pressure bar is bottomed out on plate mounds, 
tightening the screws is superfluous. If it's not, tightening 
the screws is also superfluous if the counter bearing angle 
already exists. There are at least a couple of things a tech 
can do by way of periodic maintenance to a piano that might 
qualify as beneficial to the instrument. This doesn't 
rationally qualify as one of them.

Just say no.
