TWH-NRH Range - Metric

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.
