Abstract
A tool for setting internally threaded blind-rivet nuts comprises a pliers-type structure having a fixed arm having at one end thereof a hammerhead housing formed with a bore in which a pulling piece is linearly guided. A mandrel having an external threaded part for screwing into a blind-rivet nut removably clamped in this pulling member and can be dislodged by forcing it through the pulling member and out of the end remote from the end of the head at which the blind-rivet nut is to be set. The housing is formed with a stop screw which can be indexed in place to limit the displacement of a movable arm on the housing which arm is connected with the pulling member and establishes the stroke thereof.
