Single Helix Heat Shield Fastener with Anti-Stripping Feature

A fastener, comprising:

• a substantially circular shaped body having a dish-shaped interior including an inner flat plate integrally connected to and recessed with respect to an outer planar ring;
• multiple connecting legs integrally connecting the inner flat plate to the outer planar ring;
• the outer planar ring having a substantially circular perimeter;
• and
• first and second deflectable wings each extending outwardly from the perimeter of the outer planar ring and each integrally connected to the perimeter of the outer planar ring by pairs of first and second deflectable arms, the first and second deflectable wings adapted to directly contact opposed ones of multiple faces of a socket tool when the fastener is received in a socket cavity of the socket tool.

A method for installing a fastener to limit a torque applied, the fastener having a circular shaped body having:

• a dish-shaped interior including an inner flat plate integrally connected to and recessed with respect to an outer planar ring, multiple connecting legs, an outer planar ring, and first and second deflectable wings, the method comprising:
• integrally connecting the first and second deflectable wings to a perimeter of the outer planar ring such that the first and second deflectable wings extend outwardly of the outer planar ring;
• positioning the first and second deflectable wings in direct contact with opposed ones of multiple faces of a socket tool during insertion of the fastener into a socket cavity of the socket tool;
• and
• rotating the socket tool until a predetermined torque value is applied to the first and second deflectable wings, the predetermined torque value acting to inwardly deflect the first and second deflectable wings such that the first and second deflectable wings release inwardly away from the opposed ones of the multiple faces of the socket tool.
