Abstract:
A self-locking bolt assembly ( 1 ) includes a split bolt ( 2 ) and a screw set pin ( 3 ). The bolt includes a threaded shank ( 4 ), an axial bore ( 6 ) extending through the shank, the bore ( 6 ) including a threaded bore section ( 6 A), a tapered end section ( 6 C), and a bore midsection ( 6 B) between the threaded bore section and the tapered end section. The screw set pin ( 3 ) includes a screw section ( 10 B) having threads for engaging the threaded bore section ( 6 A) and a pin shaft ( 10 ) having a tapered end section ( 10 A) for engaging the tapered end section ( 6 C) of the bore ( 6 ), the pin shaft ( 10 ) having a proximal end attached to the screw section ( 10 B). The pin shaft ( 10 ) is sufficiently long to ensure that the screw set pin ( 3 ) further into the bore ( 6 ) without galling threads of the screw section ( 10 B). The tapered end section ( 10 A) of the pin shaft has a taper angle (alpha) that is less than a taper angle (beta) of the tapered end section ( 6 C) of the bore ( 6 ) to allow a narrowed end portion of the tapered end section ( 10 A) of the pin shaft ( 10 ) to engage a narrowed end portion of the tapered end section ( 6 C) of the bore ( 6 ).
