Removable fastener with elastic linking means

A removable threaded fastener comprising:

• a head component for the application of torque having a lip portion and a lower portion of smaller diameter than said lip portion, said lower portion being unitary and coaxial with said lip portion;
• an externally threaded shank component;
• a resilient linking means connecting said lower portion and said shank component on a common axis, said resilient linking means of smaller diameter than said shank component;
• and
• said fastener having a longitudinal hexagonal opening along said common axis adapted to receive a tool in driving engagement with said head and shank components and said resilient linking means for the application of torque simultaneously thereto.

A method for removably fastening a plate member to an internally threaded work piece using a threaded fastener which comprises:

• a head component, an externally threaded shank component, a resilient linking means connecting said head and shank components, said fastener having a longitudinal opening adapted to receive a tool in driving engagement with said shank component for the application of torque thereto, said method comprising:
• threadedly engaging said fastener with said threaded aperture in said work piece;
• inserting said tool into said longitudinal opening;
• and
• applying torque to said shank component sufficient to cause axial displacement of said shank component against the resilient biasing of said linking means to maintain said head and shank components in axial tension, said torque being applied simultaneously to said head component and said shank component sufficient to cause said head component and shank component to rotate equally.
