- Bolted joint: precise, zero backlash operation of pliers
- Non-slip plastic coating on the handles
Short assembly time, long service life
Secure holding/installing of large circlips even in confined spaces
In sectors like plant construction or mechanical engineering, as in manual trades, economic efficiency of processes is key. Assembly time = production time. Precision pliers save time. Professional tools like the Knipex 48 21 J31 precision circlip pliers enable circlips to be installed and removed from holes in the shortest possible time. Every step works because the extremely stable, cold-formed tips immediately grip the mounting holes of the circlip and hold the circlips securely on the pliers.
Extremely stable, inset tips: spring steel wire for long service life
This Knipex 48 21 J31 precision circlip pliers are ideal for the installation of circlips on large shafts. Their tips of the pliers offer almost unbeatable stability. Made from high-density spring steel wire, they are interlocked in the pliers and compressed using the cold forming process. The pliers can always be relied upon for a secure grip.
Pliers head angled 90°: circlips can be easily accessed and held securely
The bolted joint of the Knipex 48 21 J31 precision circlip pliers can be set much more precisely than riveted joints. This results in a remarkably smooth joint movement with zero backlash. The pliers head is angled 90°, so that circlips can be reached with ease when access to the circlip is otherwise impossible.
