Ratchet Spanners

A Ratchet spanner is a spanner that has an open ended ring head or flare to turn a fastener in one direction but not the other direction whilst remaining fitted to the fastener head.

Ratchet spanners are useful because they don't need to be removed from the head and relocated every time the limit of the turning arc is reached. They are turned back and forth repeatedly but the nut is only turned in one direction. Some ratchet spanners have arrows etched into the surface of the tool to indicate which direction the torque is. Ratchet spanners can have two ratcheted heads or one ratchet and one non-ratcheted head. The non-ratcheted head can start or finish the task when the fastener is at its tightest and the ratchet head can do the rest.

Ratchet Head Types
•Ring Head: The most common head type is the ring head they have a 12 point profile made from a plastic component which twists in one direction within the spanner head housing.


•Reversible: Some spanners have a reversible head which accommodate two sizes, one on each face of the spanner. A lever has to be moved across to change the direction of the ratchet mechanism.


•Flare Nut Spanner: Flare nut spanners can be ratcheted too


•Open Ended Spanner: These can also have a ratchet mechanism although instead of the ratcheting mechanism being on the inside of the spanner, a spring loaded pawl a spring sticks out of one face of the profile and the fastener head acts as the gear.


•Ratchet Open ended: These have a modified profile which catches on the fastener in one direction but not the other. Turning the spanner over changes the direction of torque.
