How do I know if I need a metric jam nut for a 2011 Ford F53 chassis (Winnebago Itasca)?
Dicor Versa Liner 9/16'' Stainless Steel Encapsulated Jam Nut
One of your answers to another question on this chassis said: "The correct jam nut for a Winnebego F53 Chassis with 10 lugs and 5 hand holes, wheel size 19.5" is the V195F9-EJN. If you need the metric fine threading, use the V195F9-EJN-MF." How do I tell if I need the metric one or the other?
