Abstract
A fastener and a specialized driver, the fastener comprising a fastener head with aperture centered therein and fastener body extending from connection with the fastener head. The fastener body has an interior cavity along a length of the fastener body and a spring biased plunger is slidable within an interior cavity of the fastener body between a first position where the plunger has a surface configured to fit within the aperture and in a second position the plunger is spaced apart from the aperture. The driver is removably coupleable to the fastener to depress the plunger and transfer torque to the fastener for installation without damage to the fastener.
Claims6
A fastener system comprising:
- a fastener head having an aperture therein for receiving a head of a plunger;
- a fastener body having an externally threaded length and an open cavity along a length thereof;
- a driver having driver head with a protrusion thereon with dimensions of the protrusion substantially matching dimensions of the aperture in the fastener head and the driver having an undercut portion between the driver head and protrusion thereof allowing for transfer of torque from the driver to the fastener head without damage thereto,
- wherein the plunger head is slidable within a depth of the aperture of the fastener head from a first position wherein a top surface of the head of the plunger is flush with a top surface of the fastener head thus obscuring the aperture in the fastener head and a second position wherein the top surface of the head of the plunger is below the top surface of the fastener head.
