Abstract
A device for installing a threaded bush into a work piece has a housing containing a rotatable threaded rod. A pressure responsive piston in the housing axially moves the threaded rod with respect to the housing. A rotatable abutment sleeve is provided between the housing and the threaded rod. The bush is initially threaded on the rod and then screwed in the workpiece by rotation of the rod until a collar of the bush contacts the surface of the workpiece. Thereafter the rod is axially retracted to cause the abutment sleeve to deform a smooth walled portion of the bush to complete the installation.
