Document Type and Number:
Japanese Patent JPH04505727
Kind Code:
A
Abstract:
A fastening system including a swage type fastener including a pin and a collar adapted to be swaged into helical lock grooves in the pin and with the collar having a female thread which is threadably engageable with the helical lock grooves to selectively clamp or locate the workpieces relative to each other more or less prior to swage, with the collar thread being of a strength to deform or shear relative to the pin threads in response to a relative axial load between the pin and collar at the initiation of the swage operation but prior to swaging and in which the fastener includes a resistance member for permitting pre-clamping of the workpieces together at a selected pre-assembly pre-load while subsequently permitting sufficient relative axial movement between the pin and collar after pre-clamping such that the collar threads can be deformed or sheared prior to initiation of swage whereby the final clamp-up load of the workpieces is substantially uninhibited by the initial threaded engagement of the pin and collar threads.
