How to use a torque spanner when loosening? Upside down? On reverse pitch?

- Categories : Tutorial

This tutorial explains how to use a torque spanner "upside down", i.e. counterclockwise, when loosening. This is particularly useful when tightening on a reverse thread.

Required tools:

  • Torque spanner
  • Torx spanners or Phillips screwdriver

Duration of the operation: 2 minutes

The operation consists of turning the tip of the torque spanner so that it can torque a screw or nut with an inverted pitch, counterclockwise. This type of reverse thread is found on shafts/nuts on maxiscooters (Piaggio, Aprilia, Gilera, BMW etc...).
