Types of Fork Joint Shafts





	The snap-on spring pin is easily mounted and dismantled. It is therefore particularly suitable for applications where the articulated connection needs to be loosened often









	The pin with side mount ring can be fitted and dismantled without tools, i.e. by hand.










	The pin with safety clip requires a tool for dismantling (e.g. a screw driver). It is therefore better secured.
