Document Type and Number:
Japanese Patent JP3441084
Kind Code:
B2
Abstract:
A self-locking fastener system comprises a pin (12) for receipt in a hole in a workpiece and having an external thread (20) which mates with a collar (10) having an internal thread (18) for carrying a tensile load. A plurality of helically extending flutes (22) in the external thread on the pin (12) collectively extend approximately one full revolution around the circumference of the thread (20). The collar has three longitudinally extending lobes (28) for driving by a deltoid driver socket. When a desired clamp-up load is achieved on a workpiece, the socket plastically deforms the lobes and collar material radially inwardly thereof so that some of the collar material inwardly from each lobe is displaced into the void volume created by a helical flute (22). This displaced collar material inhibits unscrewing of the collar from the pin.
