2903 Series Nylon Ball Linkage (M4, 24.5mm Length) - 4 Pack

This nylon ball linkage has a female shank which allows an M4 fastener or threaded rod to form threads as it’s inserted.  The steel ball end is able to swivel freely inside the nylon body so that your linkage assembly transfers the force acting on it without robbing unnecessary power.  The included cupped washer can be used in order to increase the range of motion by adding clearance between the body and the fastener that is used to attach the ball to your control surface.
