When I need screws for player piano work I call Schaff Piano Supplies
unlisted division.  This was formerly American Piano Supply and I think
is now Saddler Fastner.   This other division has a fax number of
1-973-777-0481.

Screws are sold by the box only.  I fax my orders with a VISA number
and all the information on the screw.  Specify round head, slotted,
plain steel or nickel plated or brass plated, and the size such as 6X1.
You can also order flat head type screws, oval head screws, etc.  You
can order Phillips head or slotted head.
