Claims
- 1. A fastener system comprising:
- a shaft having an expander retaining structure and a threaded portion thereon;
- an expander configured for disposition and engagement in a receptacle at least partially defined by a surface, said expander having a wall defining a bore, said expander having an end for receiving at least said threaded portion of said shaft in said bore, at least a portion of said wall of said expander being threaded for receiving said threaded portion of said shaft, said expander retaining structure on said shaft retaining said expander thereon when said threaded portion of said shaft is received by said expander;
- expander actuating structure on at least one of said shaft and on said expander for actuating said expander causing said expander to engage with said surface; and
- a flange surroundingly securing said shaft for axially biasing said fastener along an axis generally coaxial with a longitudinal axis of said shaft.
- 2. A fastener system as recited in claim 1, wherein said flange is captively retained against said shaft by an annular rim on said shaft.
- 3. A fastener system comprising:
- a shaft having an expander retaining structure and a threaded portion thereon;
- an expander configured for disposition and engagement in a receptacle at least partially defined by a surface, said expander having a wall defining a bore, said expander having an end for receiving at least said threaded portion of said shaft in said bore, at least a portion of said wall of said expander being threaded for receiving said threaded portion of said shaft, said expander retaining structure on said shaft retaining said expander thereon when said threader portion of said shaft is received by said expander, said expander retaining structure comprising a head on an end of said shaft adjacent said threaded portion thereof, said head contacting said end of said expander;
- expander actuating structure on at least one of said shaft and on said expander for actuating said expander causing said expander to engage with said surface; and
- a flange surroundingly securing said shaft for axially biasing said fastener along a longitudinal axis generally coaxial with an axis of elongation of said shaft; a ring between said expander and said flange, said expander retained between said head at said end of said shaft and said ring, said flange engaged against said ring thereby causing said ring to press against said expander, said pressing further causing said expander to expand against said surface.
- 4. A fastener system as recited in claim 3, wherein said flange is captively retained against said shaft between an annular rim on said shaft and an outwardly extending collar on said shaft.
- 5. A fastener system as recited in claim 3, wherein said flange is retained between an annular rim on said shaft and a collar lockingly swaged into said shaft.
- 6. A fastener system as recited in claim 5, wherein collar is lockingly swaged into an annular groove on said shaft.
- 7. A fastener system as recited in claim 4, wherein said annular rim is at an end of said shaft, and wherein said end of said shaft and said flange are overmolded by a pad.
- 8. A fastener system comprising:
- a shaft having an expander retaining structure and a threaded portion thereon;
- an expander configured for disposition and engagement in a receptacle at least partially defined by a surface, said expander having a wall defining a bore, said expander having an end for receiving at least said threaded portion of said shaft in said bore, at least a portion of said wall of said expander being threaded for receiving said threaded portion of said shaft, said expander retaining structure on said shaft retaining said expander thereon when said threader portion of said shaft is received by said expander;
- expander actuating structure on at least one of said shaft and on said expander for actuating said expander causing said expander to engage with said surface, said expander retaining structure comprising a head at an end of said shaft adjacent said threaded portion thereof, said shaft having another head at a second, opposite end thereof overmolded by a pad, said expander spreading structure comprising a expander engaging ramp on said shaft, said fastener system further comprising a retainer between said head at said end of said shaft and said expander, said expander retained between said retainer and said expander engaging ramp on said shaft, said expander engaging ramp engaged against said expander thereby causing said expander to expand against said surface.
- 9. A fastener system comprising:
- a shaft having an expander retaining structure and a threaded portion thereon;
- an expander threadably engaged with said threaded portion of said shaft and configured for disposition and engagement in a receptacle at least partially defined by a surface, said expander having an internal wall defining a threaded bore receiving said threaded portion of said shaft, said expander retaining on said shaft retaining said expander thereon when said threaded portion of said shaft is received by said threaded bore of said expander, said expander engaging said surface upon rotation of said shaft after said expander and said shaft engaged therewith have been received by said receptacle, said expander retaining structure comprising a head at an end of said shaft adjacent said threaded portion thereof, said fastener system further comprising a ring between said expander and said flange, said expander retained between said head at said end of said shaft and said ring, said flange engaged against said ring thereby causing said ring to press against said expander, said pressing causing said expander to expand against said surface.
- 10. A fastener system as recited in claim 9, said expander retaining structure comprising a head at an end of said shaft adjacent said threaded portion thereof, said fastener system further comprising an expander engaging ramp on said shaft; a retainer between said head at said end of said shaft and said expander, said expander retained between said retainer and said expander engaging ramp on said shaft of said fastener, said expander engaging ramp engaged against said expander thereby causing said expander to expand against said surface.
- 11. A fastener system as recited in claim 9, further comprising a flange captively retained against said shaft between an annular rim on said shaft and an outwardly extending collar on said shaft.
