Quality Rod End -  5/16" / 8mm Ball x 5/16' Right Hand Female
 
2-piece Rod End - The ball is inserted into the body and the body is then swaged around the ball to lock it in and it is then loosened to allow it to move. The body is made from Carbon Steel. These joints are ideal for use in areas which do not have a large force present or for gear/throttle linkages or where vibration may be heavy at the ball. These joints should be kept lubricated.
