Self-retained bolt

Claim 1

A bolt comprising: a. a head having a shank extending axially outwardly from said head terminating in an end face, said head further having an inner surface directed toward said end face and defining a plane surface substantially perpendicular to said axially extending shank; b. a generally radially extending recess opening at the circumferential periphery of the shank terminating radially inwardly from said circumferential periphery and terminating axially outwardly from said head; c. a pawl mounted at least partially within said recess for generally radial movement between an extended position and a retracted position; d. said pawl having an inner end face directed toward said head and defining a plane surface substantially parallel with said head plane surface so that said pawl is unmovable from the extended position to the retracted position by forces directed generally axially against said pawl inner end face; e. said pawl having a cam surface which extends radially inwardly as it extends axially outwardly toward said end face; f. a pair of concentrically arranged coil compression springs disposed within said recess generally radially of said pawl urging said pawl toward the extended position, said springs resiliently yieldable in response to a generally radially directed force against said pawl when said pawl is n the extended position; g. a stop formed integrally with said shank; and h. a shoulder on said pawl engageably with said stop to prevent said pawl from being forced out of said recess by said springs.
