Abstract: A method of forming a joined pair fo wedge-action-type lock washers, wherein each lock washer has a cam surface and an oppositely disposed friction surface, the pair of washers being arranged so that their cam surfaces are installed in a juxtaposed face-to-face engagement, at which time the two lock washers are selectively joined together in such a manner as to allow lateral movement between each washer when rotational force is applied during the tightening of an associated fastening device.
