FASTENER AND METHOD OF INSTALLING THE SAME

Document Type and Number:

Japanese Patent JP2011231932

Kind Code:

A

Abstract:

To provide a fastener which can be installed into a workpiece by either swaging or torquing methods so that the types of fasteners used by manufacturers can be reduced.

A fastener (20) is installed into a workpiece (28) by either a swaging operation or a torquing operation. The fastener includes an enlarged protruding head (22) which is substantially positioned at a proximal end side than a cylindrical smooth shank portion (30). A threaded shank portion (38) positioned at a distal end side of the smooth shank portion includes a male thread, which has sufficient strength to have a swage collar (46) swaged onto it. At a distal end side of the threaded shank portion, a pin tail portion (48) is provided which has a surface shaped to be engaged with a tool. Between the threaded shank portion and the pin tail portion, a narow-neck groove (50) is provided which has lower tensile strength than any other portion of the fastener.
