Three-axes variability compensating fastener

An apparatus for securing a component to a panel to provide variable positioning of the component with respect to three mutually perpendicular axes, said apparatus comprising:

• an elongate, threaded stud having a first shank portion for threaded attachment to said component, a second shank portion and a flange formed integrally therebetween;
• a generally planar member adapted to be positioned axially intermediate one side of said panel, said member having a generally cylindrical, elongate collar projecting perpendicularly from the plane thereof, said collar having internal threads formed therein for threaded attachment to said stud second shank portion such that said stud is variably axially positionable along its axis of elongation, and external threads formed in an opposite direction on an outer surface thereof, said collar being adapted to be inserted into an aperture formed in said panel, said aperture being sized to provide substantial diametrical clearance about said collar outer surface;
• an internally threaded nut threadedly engageable with said external threads of said collar formed integrally with a generally planar disc adapted to abuttingly engageable an opposite side of said panel, said disc including a plurality of ribs integrally formed on one side thereof, each of said ribs including a deformable projection tip operative to flatten and seal said aperture upon clamping engagement of said planar member and said nut to said panel, whereby upon tightening said nut, said planar disc is drawn against said panel to clampingly engage said panel to secure said component in a desired position.

A mounting system for securing a component to a panel, comprising:

• an elongate, left-hand threaded stud having a first shank portion for threaded engagement with said component, a second portion and a flange formed integrally therebetween;
• a hole formed through the panel being sized to permit insertion of the stud along its axis of elongation to provide substantial diametrical clearance therebetween;
• a fastener assembly variably axially positionable along the stud axis of elongation, carried within the diametrical clearance and clampingly secured to the panel to provide variable positioning of the component with respect to three mutually perpendicular axes, said fastener comprising:
• a generally planar member adapted to be positioned axially intermediate one side of said panel, said member having a generally cylindrical, elongate collar projecting perpendicularly from the plane thereof, said collar having internal threads formed therein for threaded attachment along the length of said stud second shank portion and external right-hand threads formed on an outer surface thereof, said collar being adapted to be inserted into said hole;
• an internally threaded nut threadedly engageable with said external threads of said collar, said nut being formed integrally with a generally planar disc adapted to abuttingly engageable an opposite side of said panel, said disc including a plurality of ribs molded integrally therewith, each rib including a deformable projection top extending therefrom and operative to seal said aperture upon clamping engagement of said planar member and said nut to said panel, whereby upon tightening said nut, said planar member and said disc are drawn against said panel to clampingly engage said panel to secure said component in a desired position and said projection tips are flattened against said panel to provide watertight sealing around said hole.
