I would like to know where I could find a good source of hard-to-find
nuts, bolts, fasteners, screws, gears, and other metal pieces not really
available at the local hardware.

I was at Home Depot and among their vast assortment of screws they had no
square nuts, and no fasteners like the ones I was looking for.  Another
thing that I didn't like was how their screws were made with a mirror-
like coating which was so new and shiny looking it didn't fit my piano at
all, plus it was a little too long.

Specifically, I would like the address for the Boston Gear Co.
