Please note this nut and bolt is 3/16” thick and is exclusive to Gen. 1 DLX 900 and DLX 1200 Oklahoma Joe’s Pellet Grills that use the 3″ square motor type. All of the current grills (Gen. 2) pellet grills use a thinner 1/8″ nut and bolt which can be found here.
All of the OEM Oklahoma Joe’s Pellet Grill Auger motors that we sell come with the respective shaft hardware for the model based on the model # on the grill lid.
This bolt and nut are responsible for securing the shaft of the auger motor. If this part is missing the motor will turn but the auger will not.
