The plow bolt is 3" inches long and 7/16" inch in diameter and SAE grade 5.
Washer is a USS spec. flat washer (USS specification washer is slightly larger in outside diameter and thicker than the standard normal "big box store" SAE specification flat washer) to prevent bending.
Hex Nut is HEAVY DUTY for plow bolt use.
These are from the same source that supplies a MAJOR USA farm equipment manufacturer.
These are high quality parts that will provide years of service in demanding conditions.
Try a couple or more, you will not be disappointed!!!
