This is an item for farm tractor implements called a "lower link pin" and is used when connecting a tractor to an implement. You state the pin is 1.1" in diameter (which is actually 1-1/8" for a "category 2" hitch. Since these pins are a wear item, they are literally thousands of different types of pins available on the farm aftermarket supply. This is because the attachment to an implement can be nearly any bolt hole of any depth, while the other end of the pin must correspond to the sizes specified in category 0,1,2 or 3.
