Abstract
A power hand tool for setting internally threaded rivets comprising a housing having a motor which drives a mandrel that screws into the rivets and compresses them against an anvil forming part of the housing. The connection between the motor and mandrel includes a spindle driven by the motor and having a chamber at one end which receives a mandrel driver that in turn carries the mandrel. A spring in the chamber behind the driver yieldably urges the mandrel in the direction of the rivet to be set on the mandrel.
