FB - Model Type A -Leaf Chain Pin

Often referred to as a top hat pin, we refer to this pin as type “A”.  They have one hole at the end for a split pin/cotter pin and a head which is larger than the leaf chain pin diameter.  The manufacturing process can be expensive as they require plunge grinding. They can only be removed from one side, can be useful where lateral space is limited and where concerns exist that the pin will snag on other components.
