Abstract: A washer-lock washer is disclosed that can be used with a fastener. In one form the washer-lock washer is integrally connected. In another form the washer-lock washer is joined together from two separate pieces. The washer-lock washer may be provided with additional locking features, which would include nubs, indentations, protrusions or cones. This latter concept of the present invention can also be incorporated into a separate lock washer. In another form, the lock washer portion is a separate piece with additional locking features. In another form the washer-lock washer is combined with a fastener. In another form, the washer portion of the washer-lock washer can be welded in place to the mating part or secured by some other means. The washer-lock washer and washer lock-washer fastener combination expedites assembly of products using the same, and can be used to hold together parts in conjunction with either a threads in one of the parts or a separate nut.
