Claim 1

AN IMPROVED DISCRETE LOCK NUT BODY FOR FORWARD AND BACKWARD ROTATION ON A THREADED STEM INTO AND OUT OF A TIGHT-VIBRATION-RESISTANT LOCKING ENGAGEMENT WITH A TRANSVERSE SUBSTANTIALLY PLANAR END ABUTMENT SURFACE HAVING AN AREA AT LEAST EQUAL TO THE TRANSVERSE AREA OF SAID BODY, SAID BODY HAVING SUBSTANTIALLY PLANAR VERTICAL SIDE WALLS DEFINING VERTICAL CORNERS THEREBETWEEN, A SUBSTANTIALLY PLANAR TRANSVERSE OUTER END WALL, A THREADED BORE EXTENDING CENTRALLY THROUGH SAID BODY NORMAL TO SAID PLANAR OUTER END WALL, AN OPPOSED TRANSVERSE INNER END OPERATING WALL TO BE MOVED INTO AND OUT OF A TIGHT COMPRESSION-LOCKING ENGAGEMENT WITH RESPECT TO THE PLANAR END ABUTMENT SURFACE BY A FORWARD ROTATION OF SAID BODY ON THE THREADED STEM, SAID INNER END OPERATING WALL HAVING A PLANAR ABUTMENT FACE PORTION SUBSTANTIALLY NORMAL TO SAID THREADED BORE AND EXTENDING TRANSVERSELY FROM ONE SIDE WALL HALF OF SAID BODY TOWARDS AN OPPOSITE SIDE WALL HALF THEREOF IMMEDIATELY TO AND PARTIALLY ALONG OPPOSITE SIDES OF SAID THREADED BORE, SAID INNER END OPERATING WALL HAVING A TRANSVERSE OFFSET FACE PORTION DECLINING FROM SAID ABUTMENT FACE PORTION TOWARD SAID OUTER END WALL AND EXTENDING TO SAID OPPOSITE SIDE WALL HALF OF SAID BODY, SO THAT SAID BODY WILL BE COCKED ON THE THREADED STEM BY COMPRESSION-ABUTMENT OF SAID ABUTMENT FACE PORTION WITH THE PLANAR END ABUTMENT SURFACE WHEN SAID BODY IS ROTATED FORWARDLY ON THE THREADED STEM INTO TIGHT ENGAGEMENT THEREWITH, ALTERNATE GROOVES AND LANDS FORMED IN AND EXTENDING CONTINUOUSLY TRANSVERSELY FULLY-ACROSS SAID ABUTMENT FACE PORTION BETWEEN THE ONE SIDE WALL HALF OF SAID BODY IMMEDIATELY TO AND PARTIALLY ALONG OPPOSITE SIDES OF SAID THREADED BORE, SAID LANDS BEING DEFINED BY SAID GROOVES AND HAVING SUBSTANTIALLY PLANAR SIDE WALLS THAT ARE NORMALLY IN SUBSTANTIALLY PARALLEL POSITIONS TO A PLANE CONTAINING THE AXIS OF SAID THREADED BORE AND TO EACH OTHER, SAID SIDE WALLS OF SAID GROOVES AT THE MIDPORTION OF SAID ABUTMENT FACE PORTION EXTENDING IN A GENERALLY RADIAL DIRECTION, SAID LANDS AND GROOVES BEING SUBSTANTIALLY OF EQUAL CROSS SECTIONAL AREA, SAID AREA BEING OF SUCH A SIZE AS TO PERMIT THE LANDS TO BE FLEXIBLE AND ADAPTED TO DEFORM WITHIN THEIR ELASTIC LIMITS FROM THEIR NORMAL SUBSTANTIALLY PARALLEL POSITIONS TO BACKWARDLY-BENT POSITIONS WITHIN SAID GROOVES WHEN SAID BODY IS TIGHTENED-DOWN ON SAID PLANAR ABUTMENT FACE PORTION BY FORWARDLY-ROTATING IT ON THE THREADED STEM.
