More info

The ratcheting action of a wrench or screwdriver is designed to maximise every turn, perfect for when you have a screw, nut or bolt that needs a firm connection or is proving difficult to loosen.

Saving your hands and wrists from the fatigue of a repetitive turning action, this 21mm combination ratcheting wrench from reputable tool manufacturer Bahco offers another benefit: a swivelling head.

Getting a firm grip on a nut or bolt is essential when using a wrench – it minimises potential injury to your hand and wrist, as well as completing the action quickly and without damaging the nut or bolt. But getting a firm grip is difficult when space is limited or you are working in an awkward space. This swivel head combination ratcheting wrench solves those issues.

The swivel head on this spanner moves through 180° in 15° ‘steps’ allowing you to lock the head into the perfect position. The 12-point dynamic drive also limits wear and tear on nuts and bolts, ideal for when removing or tightening the same fastening on a frequent basis.

As well as its moveable head at one end, at the other, you have an open head with a 15° angle for better purchase on nuts and bolts. It’s slimmer profile also improves accessibility.

This 21mm combination ratchet wrench conforms to ISO 3318:2016 assembly tools of nuts and screws, as well as DIN 3113, a German standard for tools.
