Plastic nut with retaining elements to hold the nut in a socket of a tool

A plastic nut adapted to hold the nut in a socket of a tool, the nut comprising:

• a polygonal portion including a plurality of adjacent faces meeting at a plurality of longitudinal edges, the polygonal potion defining a longitudinal central bore;
• and,
• at least one outwardly projecting tapered rib formed on a corresponding longitudinal edge;
• and
• wherein the tapered rib is deformable by the tool socket in order to engage the socket and retain the nut in the socket when the nut is inserted in the socket, and
• the tapered rib includes a leading end and a trailing end and defines an axial length between the leading end and the trailing end;
• the tapered rib defines a radial depth and the radial depth of the of the rib increases from the leading end to the trailing end;
• and
• the maximum radial depth of the rib is significantly less than the axial length.
