Rega Torque Wrench for Optimum Cartridge to Tonearm Coupling (0.4Nm).
Rega's torque wrench takes the guess work out of cartridge mounting.
For years Rega has recommended evenly torquing the screws that hold the cartridge in place. By doing so the force applied to the cartridge body is both even and precise.
This insures an optimum coupling between the cartridge and arm.
