Speed nut and assembly

A fastener device comprising:

• a body having a surface comprising a central opening;
• a plurality of separated flexible segments extending inwardly from the central opening of the surface and evenly spaced circumferentially about the central opening, the distal end of each segment comprising an internal threaded portion;
• and
• a plurality of inwardly projecting centering portions respectively spaced circumferentially between adjoining segments.

A fastener device comprising:

• a first body having a surface comprising an opening circumscribing a central axis;
• a plurality of separated flexible segments extending inwardly and downwardly from the opening at the surface, the segments spaced circumferentially about the central opening, wherein the distal end of each segment comprises an internal threaded portion;
• and
• a second body overlaying the first body surface, the second body comprising a cylindrical opening having an axis coincident with the central axis, the diameter of the cylindrical opening less than the a radial distance across the first body surface opening;
• wherein the cylindrical opening is configured to align an externally threaded fastener engageble with the threaded portions of the segments.

A fastener device comprising:

• a first body having a surface comprising an opening circumscribing a central axis;
• a plurality of separated flexible segments extending inwardly and downwardly from the opening at the surface, the segments spaced circumferentially about the central opening, wherein the distal end of each segment comprises a first internal threaded portion to collectively form a first internal thread;
• and
• a second body overlaying the first body surface, the second body comprising:
• a first surface in contact with the surface of the first body and comprising an opening circumscribing the axis;
• a second surface opposite the first surface, the second surface comprising an opening circumscribing the axis;
• and
• a plurality of separated flexible segments spaced circumferentially about the second surface opening and extending inwardly therefrom.

A fastener device:

• a plurality of bodies, each body comprising:
• a surface having a central opening;
• a plurality of separated flexible segments, each segment comprising an arm of rectangular cross section that extends inwardly from the central opening of the surface, the distal end of the segment comprising an internal threaded portion;
• and
• a flexible tab having a barbed end and a notch;
• wherein the tab and notch are configured for latching each of the plurality of bodies to a another said fastener body, thereby to form a stacked multithreaded structure engageable with an externally threaded fastener.
