The is an Open Ended Spanner with ring ratchet. It is made of vanadium steel 31CrV3. The open end is suitable for loosening tightly-fitting bolts. The ring ratchet is for ratchet loosening and fast tightening. No more repositioning necessary - this is the modern way to tighten bolts. Fine toothed 72 teeth and a very low constructional height make the 7 R range an indispensable aid in places where the normal ratchet is too large or clumsy. Astonishingly high torque transfer - the DIN requirements are exceeded.
