  • Threaded cold working mandrel
    Patent number: 5038596
    Abstract: A mandrel assembly is utilized to cold work a hole in a structural member which is present in a confined area. A mandrel and sleeve are slipped through one end of the hole. The mandrel length is threaded so that a nut may be turned along its length. Between the nut and the structural member are jaws which retain the sleeve within the hole while the nut is turned. The outward end of the mandrel is fixed by means of clamping flats formed on the outward end so the mandrel may be drawn through the sleeve within the hole as the nut is tightened against the intermediately positioned washer and jaws.
