More than you should ever want to know about Screwhead Types

[Robert C.Abell]

The " Robertson" name I believe is a Canadian identity for the square head screw slot.

I used to have the " Robertson" factory in Milton, Ontario as a customer when I handled
insurance claims for their parent corporation the Marmon Group out of Chicago, Ill.
