Types of Ring Spanners

The ring end recess is generally a six-point or twelve-point opening and sometimes offers a ratchet mechanism that helps apply maximum force with minimal user effort. Ring spanners are available in most metric (mm) and imperial (inch) sizes to allow for greater functionality across a wider range of applications.

How do ring spanners work?

Ring spanners rely upon the physical strengths of the user to deliver accurate force when attaching the recessed head to the fastener and rotating clockwise or anti-clockwise. Depending on the material they are made from, they can often withstand large amounts of torque being applied to stubborn fasteners.
