ABSTRACT:
The invention provides a terminal clamp assembly comprising a fastener and one or more captive members and a method for making such a terminal clamp assembly. The terminal clamp assembly comprises a threaded fastener including a driver head portion, a threaded shank portion of predetermined thread crest diameter and an unthreaded shank portion of lesser diameter intermediate the threaded shank portion and the driver head portion. A captive member has a through aperture of greater diameter than the thread crest diameter and surrounding the unthreaded shank portion, and laterally oppositely outwardly extending protrusions on opposed outer edge portions. These protrusions are compressed by a planar die so as to deform the through aperture to a dimension smaller than the thread crest diameter, thereby captively assembling the captive member with the fastener, subsequent to formation and heat treatment of the fastener.
