A fastener for installation into a workpiece which may be installed by either a swaging operation or a torquing operation. Tensions on the suspension members apply torques to a load transfer linkage comprising a plurality of horizontally extending, torsionally rigid torque transfer members arranged for additive transfer of the torques to a lever counterbalancing and indicating device. The inlet mouth is fluidically connected to the compartment to supply it with the fuel in order to lubricate andor cool the pump itself.
