ABSTRACT:
A washer assembly which may be assembled and locked into place without fully removing a bolt or screw is described herein. The assembly is comprised of at least two identical segments, each having a male end and a female end. The segments are fitted together, preferably along a planar axis the male end of one segment fitting into the female end of the second segment; and the male end of a second segment fitting into the female end of the first segment. The male end is comprised of a flattened tongue, preferably circular, having convex nodules on at least one surface of the tongue. The female end is comprised of two flattened essentially parallel leaves forming the opening of a slot. At least one inner surface of this slot has at least one complementary concave depression. When the flattened tongue fits into the slot the convex nodules snap into the complementary concave depressions, locking the segments of the washer assembly together. Alternatively, the tongue will have at least one concave depression on at least one surface; and at least one inner surface of the leaves of the female end will have at least one convex nodule, said nodules being received by the depressions on the tongue surface or surfaces when the male end is fitted into the female end.
