ROCKER ARM SCREWS
We manufacture and stock a variety of rocker arm adjusting screws and jam nuts. We offer various diameters, lengths and radii in both ball style and cup style with and without oil holes. Our standard screws are made from 86L20 material and we also produce and stock a lesser variety in tool steel material for more extreme applications. You will find our 86L20 offerings in our 2017 catalog on pages 10-11. To inquire about our tool steel options, please contact us.
