Fastener assembly device

A fastener assembly device for fastening workpieces together, said device comprising:

• an elongate fastener having a first and a second end;
• said fastener including:
• a head defined by said first end of said fastener;
• a threaded portion which extends between said second end of said fastener and said head;
• a shank portion disposed between said head and said threaded portion;
• and
• an annular collar disposed between said head and said second end of said fastener;
• and
• a washer cooperating with said fastener, said washer defining an aperture for the reception therethrough of said threaded portion of said fastener;
• said washer including:
• a plurality of inwardly extending protrusions adapted and arranged so that said washer snaps over said collar to secure the washer and the fastener together;
• and
• each protrusion of said plurality of protrusions being unevenly spaced circumferentially from an adjacent protrusion.

• each protrusion of said plurality of protrusions being unevenly spaced circumferentially from an adjacent protrusion;
• said head being a hexagonal type bolt head;
• said threaded portion extending from said second end of said fastener to said annular collar;
• said shank portion extending from said head to said annular collar;
• said annular collar being disposed between said shank portion and said threaded portion;
• said annular collar being integrally formed with and disposed between said shank portion and said threaded portion;
• said fastener including said annular collar being fabricated from steel;
• said washer including:
• a cylindrical portion having a first and a second extremity;
• a radially extending flange extending from said first extremity of said cylindrical portion;
• a further radially extending flange extending from said second extremity of said cylindrical portion;
• said cylindrical portion defining said aperture for the reception therethrough of said threaded portion;
• said plurality of protrusions extending radially inwards from said cylindrical portion;
• said plurality of protrusions providing an interference fit with said annular collar when said threaded portion is moved axially through said aperture;
• said plurality of protrusions including:
• a first and a second protrusion;
• and
• a first circumferential distance between said first and said second protrusions being less than a second circumferential distance between said first and said second protrusions, said first and second distances being equal to a circumference of said annular collar.
