Abstract (en)

A precision hinge joint especially useful for dental and orthodontic hand tools (10) includes a threaded fastener (32) that pivotally couples arms (12, 16) of the tool together. An outer end of the fastener is riveted into a recess (30) formed on the side of the tool to form an enlarged end portion that substantially prevents the threaded fastener from loosening during use. <IMAGE>
