In a nutshell
The right choise for
With the Knipex 45 21 200 retaining ring pliers, you can easily install and remove horseshoe-shaped retaining rings and snap rings without grip holes. Where standard circlip pliers cannot grip, the 30° angled jaws with a centering hole keep rings securely aligned on shaft diameters from 12 mm upwards with a minimum split gap of 2.2 mm. This prevents rings from slipping off or flying away when working on gearboxes and drive shaft assemblies. The integrated opening spring and plastic-coated handles ensure smooth, fatigue-free operation during repetitive tasks. Forged from oil-hardened chrome vanadium electric steel with a black atramentized finish, these pliers deliver the control and durability you need.
