Fabco hex jam nut 6880636 or 688-0636 is a 5/8-18 threaded hex jam nut used across Fabco transfer case, power takeoff, and steerable drive axle assemblies. The jam profile is thinner than a standard hex nut, which makes it useful for locking against a second nut or holding a fastener in position where clearance is limited. It carries a 5/8 inch diameter with 18 threads per inch fine thread. This is a genuine Fabco fastener sold by Pro Gear and Transmission. Not sure this is your part?
