The TWH-NRH range of metric hexagon ratchet heads, suitable for use with TWH-N series low profile hydraulic
torque wrenches, provide exceptional flexibility with across flats (AF) sizes from 24 mm to 175 mm available as standard.
All models feature extremely low profile design combined with a minimum nose radius (R) that enables
fitment in very confined limited access places. For even greater versatility a comprehensive range of metric
hexagon reducer bushes and square drive conversion kits to suit TWH-NRH metric ratchet heads are also available.
Non standard and special design ratchet heads can be made to order.
