ABSTRACT:
An improved deformable locking fastener system comprises a bolt, a deformable collar and an installation tool. The bolt has a threaded exterior for engaging the collar. The collar has an axial bore threaded to engage the bolt. The exterior of the collar is defined by a central portion and a head portion. The central and head portions preferably have an elliptical shape with the central portion slightly greater in size. The central portion and the head portion are deformed from their elliptical shapes to substantially round shapes to securely fasten the collar and bolt. The central portion advantageously generates a predetermined preloaded tension between the collar and the nut. The head portion locks the collar and bolt together because it is swaged or deformed into recesses on the threads of the bolt. A tool is used to secure the collar on the bolt. The tool comprises a cylindrical socket wrench having a central axial bore which defines a recess on one end for attachment to a socket driver and an a stepped elliptical cavity on the opposite end for engaging the central and head portions of the collar.
