This is a 3/16 (.187) diameter press-fit pivot with a .205 head. They are designed to work with a 4-40 button head screw (included). They have a slightly larger upper barrel diameter which creates a press ridge, allowing them to snuggly fit into the frame or liner. This stops unwanted pivot spin. The overall length of this model is .336 inches. They can be modified to a shorter length if desired.
