Hydraulic Lever Pump Hand Tool
The ES 51 installs the RIVNUT® by stroke distance control. The tool is operated by pumping a lever attached to a hydraulic cylinder that exerts a pull stroke on the fastener. Spin on and spin off is accomplished by rotating the central shaft spin knob. The ES 51 can exert enough force to install the largest sizes of RIVNUT® fasteners easily.
