Abstract
A glueless shaft joining system, apparatus and method are disclosed. A base insertable into the hollow interior of the shaft can include a plurality of flexible fingers separated by a slot defined between each of the adjacent flexible fingers. The interior of the base is hollow and includes a threaded portion adjacent to the distal end that extends inwards in a proximal direction. A set screw can be inserted into the threaded portion of the hollow interior of the base. The set screw includes a threaded head portion and a non-threaded tail portion that diverges as it extends away from the head portion. The tail portion deflects the flexible fingers laterally outwardly as the set screw is advanced in the proximal direction through the base. A component, such as a broad head or arrow nock can be coupled to the insert as desired.
