  • Patent number: 5829934
    Abstract: A prevailing torque clip (100) is provided that has a head portion (4) having a frusto-conical projection (10) having an aperture (6) therethrough that is provided preferably with diametrical opposed helical thread forms (8) and (8') that are operative to threadingly engage threads of a threaded member rotationally advanced therethrough. Head portion 4 includes a pair of ressilient arms (12) and (12') that end in respective free-ends (9) and (9') that are operative to engage the threads of the threaded member and cooperate with thread forms (8) and (8') to prevent loosening thereof. Clip (100) is adapted to prevent rattle when used to secure an object to thin wall panel by being provided with at least one pair of tabs (16) and (16') that are operative to elevate clip (100) from a panel to which it is being secured sufficiently to ensure that the portion of arms (12) and (12') that are in close proximity to projection (10) are positioned within the panel opening into which arms (12) and (12') are received.

  • Patent number: 5256018
    Abstract: A clip on fastener (100) is provided that features a pair of spaced apart legs (2) and (6) extending from a closed end (9) to an open end (10) of fastener (100). Leg (6) includes a pair of resilient arms (16 and 18) that extend away from the side of the leg (6) facing away from leg (2) and end in overhanging relationship to an opening (7) through arm (16). Arm (18) extends towards closed end (9) and includes a guide tab (20) that extends angularly away from leg (2) towards open end (10). Tab (20) is operative to initiate separation of legs (2 and 6) to enhance receipt of an edge of a panel or plate (P) into open end (10).
