It is designed to be welded directly to a 3.500-inch diameter steel driveshaft tube with a .134-inch wall thickness, connecting the tube to a matching 1550 series universal joint. You would typically replace this component during a driveshaft repair or modification when the old yoke is worn, damaged, or when converting a shaft to the robust 1550 joint size.
