  • Zero-clearance bolted joint
    Patent number: 7717659
    Abstract: A bolted joint which is formed by using a bolt having a tapered shoulder to cold form a deformable sleeve in order to provide a “zero-clearance” fit. Specifically, preferably a plurality of bolted joints are used to join a ring gear to a differential case. As the bolts are installed into the differential case and ring gear, tapered shoulders on the bolts dilate deformable sleeves until outer diameters of the sleeves contact internal walls of through holes in the differential case.
