ABSTRACT:
This invention provides a novel nose assembly for an installation tool for crimping or swaging nuts onto threaded bolts to form a lock-bolt combination. The nose assembly is configured such that its spindle has a bight section or slot to receive a projected head of a pull piston. This provides quick engagement and disengagement of the nose assembly from the installation tool that allows easier and faster change without the use of special tooling.
