In response to Damon Atchison's request for sources of specialty
fasteners, I'd try The Olander Company.  If they don't have it,
probably it doesn't exist and if it does exist somewhere else, they'll
usually be able to tell you where to get it.

Also included here is Boston Gear's address along with two other
companies that specialize in gears, sprockets, ladder chains,
fasteners, other specialized hardware and zillions of other mechanical
goodies.

Their catalogs are a *must* for those hard to find parts.
