Abstract

Described herein are embodiments of fastening systems that can provide easily removed and reapplied fasteners and that provide a hindrance to those that might tamper with the fasteners. In some embodiments, fasteners are also described that are configured to reduce the accumulation of dust and dirt inside the fasteners. In further embodiments, fasteners are provided for improving the aerodynamics of the fastener, and some embodiments describe provision of commercial advertising or other messages on the fastener.

Claims

1. A security fastener comprising a head having a recessed top with a circumferential wall, said circumferential wall having a plurality of indentations therein spaced below an upper edge of the wall to permit engagement of the fastener by a tool with retractable projections matable with said indentations, said fastener further comprising a cap that is sized and configured to be received within the recessed top, said cap comprising an indentation in a side of the cap for providing a pry hole, said indentation being concealed when the cap is initially inserted into the recessed top.

2. The security fastener of claim 1, wherein the indentation in the cap is also on a top surface of the cap.

3. The security fastener of claim 1, wherein the indentation in the cap is also on a bottom surface of the cap.

4. The security fastener of claim 1, wherein the recessed top comprises a plurality of protrusions extending from the circumferential wall.

5. The security fastener of claim 1, further comprising adhesive on a portion of the cap.

6. The security fastener of claim 1, wherein the cap further comprises a protrusion extending from a side of the cap.

7. The security fastener of claim 1, wherein the cap comprises material above the indentation in the side of the cap that can be broken to expose the indentation.

8. A security fastener driver for driving a security fastener that comprises a head having a recessed top with a circumferential wall, said circumferential wall having a plurality of indentations therein spaced below an upper edge of the wall to permit engagement of the fastener by the driver, said fastener further comprising a cap that is sized and configured to be received within the recessed top, said cap comprising an indentation in a side of the cap for providing a pry hole, said indentation being concealed when the cap is initially inserted into the recessed top, said security fastener driver comprising a plurality of elongate arms that extend in a longitudinal direction, said elongate arms further comprising distal portions that extend generally transverse to the longitudinal direction and are movable generally transverse to the longitudinal direction such that said distal portions are configured to extend into the indentations of the circumferential wall and engage the fastener, said driver further comprising an actuatable member that is configured to move in the longitudinal direction to move said elongate arms transverse to the longitudinal direction to engage and disengage the distal portions with the fastener.

9. The security fastener driver of claim 8, further comprising a cylindrical supporting strut that substantially encloses the elongate arms.

10. The security fastener driver of claim 9, further comprising a plurality of guides toward the distal end of the cylindrical supporting strut for guiding the distal portions of the elongate arms.

11. The security fastener driver of claim 8, further comprising a flexible portion between a handle of said driver and said distal portions.

12. The security fastener driver of claim 8, wherein the actuatable member is connected to a button located on a handle of said driver.

13. The security fastener driver of claim 8, wherein the driver comprises six elongate arms.

14. The security fastener driver of claim 8, wherein the distal portions extend at an angle of about 90 degrees with respect to the longitudinal direction.

15. The security fastener driver of claim 8, wherein the distal portions are generally cylindrically-shaped.

16. A method of using a security fastening system, comprising:

providing a security fastener comprising a head having a recessed top with a circumferential wall, said circumferential wall having a plurality of indentations therein spaced below an upper edge of the wall to permit engagement of the fastener by a driver, said fastener further comprising a cap that is sized and configured to be received within the recessed top, said cap comprising an indentation in a side of the cap for providing a pry hole, said indentation being concealed when the cap is initially inserted into the recessed top;

providing a security fastener driver comprising a plurality of elongate arms that extend in a longitudinal direction, said elongate arms further comprising distal portions that extend generally transverse to the longitudinal direction and are movable generally transverse to the longitudinal direction such that said distal portions are configured to extend into the indentations of the circumferential wall and engage the fastener, said driver further comprising an actuatable member that is configured to move in the longitudinal direction to move said elongate arms transverse to the longitudinal direction to engage and disengage the distal portions with the fastener;

advancing a distal end of the driver into the recessed top; and

moving the actuatable member in the longitudinal direction to move the distal portions of the elongate arms transverse to the longitudinal direction and to engage the indentations in the circumferential wall.
