square drive screws.

[alan forsyth]

About 5 years ago I came across an action where all the action screws had 
Robertson type heads.  Really great to work with. Can't remember what piano 
but it may have been a Hopkinson which were a heavy duty type piano meant 
for school abuse and which would be overhauled several times in it's 
lifetime.
