Fastening system

A plastic two piece fastener for maintaining two workpieces in movable juxtaposed relationship wherein each of the workpieces has a bore which may be proximate to yet misaligned with a similar bore in the other workpiece, said fastener system including a female socket adapted to be accepted in the bore in one workpiece and a double ended self-mounting male stud having a first portion adapted to be accepted in the aligned bore of the other workpiece and a second portion projecting outwardly therefrom adapted to be complementarily accepted within said female socket, said female socket having external means impinging on the wall of said bore to retain said female socket within said bore, means projecting radially inwardly of said socket to engage said second portion, said first portion of said male stud including a substantially rigid axially extending first element having laterally projecting resilient means adapted to permit ready introduction into a bore and positive retention against inadvertent withdrawal, a laterally extending flange means between said first and second portions serving generally as a head member to limit the depth of introduction of said first portion into a bore, said second portion including a coaxial means extending in the opposite direction from said first portion, said coaxial means being deflectable substantially as in precession at its end opposite said flange means and said coaxial means further having means including a curvilinear exterior surface extending outwardly from the end of said coaxial means substantially in all directions and further having at least two laterally reversley directed curvilinear means extending toward said flange means, said deflectable coaxial means of said second portion including a tapered stem generally decreasing in thickness due to a general reduction in cross sectional area as it extends away from the flange means toward said deflectable head, said curvilinear means forming a deflectable head acceptable in complementary relation within said female socket, whereby said deflectable head and said tapered stem are laterally movable as in precession and adapted to accommodate centerline tolerance variations between said two workpieces.
