Tension Spring Knipex 97 59 31 – OEM spare part, steel coil spring

Knipex 97 59 31 is a steel tension coil spring designed as an OEM spare part for compatible Knipex tools and assemblies. It provides restoring force for levers, pliers and small mechanisms that require a reliable return action. The spring is intended for repair and maintenance tasks where the original component has worn, stretched or failed, and it restores intended mechanical movement without altering the tool's original geometry.

Advantages

The steel construction ensures consistent elastic properties and resistance to deformation under normal working loads. As an OEM-compatible spare, the spring matches original dimensions and force characteristics to preserve tool ergonomics and function. Its simple, compact shape allows straightforward replacement with no modification to surrounding parts.

Suitable for

• Replacement of worn or broken return springs in Knipex pliers and hand tools
• Maintenance and restoration of lever-operated mechanisms
• Workshop repairs where an OEM-compatible tension spring is required

Key specifications

• Material: steel
• Type: tension (coil) spring
• Function: provides elastic restoring force for return action
• Form factor: compact coil suitable for integration into hand tools
• Application environment: mechanical assemblies and hand tool mechanisms

How to use

Replace the damaged or worn spring by first securing the tool in a stable position. Remove any retaining pins or clips that hold the old spring, note the orientation and seating position, and fit the new steel coil spring in the same location. Ensure the spring engages correctly with both mating surfaces and that the lever or plier arms move freely through the expected range of motion. Reinstall retaining elements and test the tool operation under light load before returning it to regular use.

Usage recommendations

Use the spring only in compatible tools and mechanisms designed for a similar tension component. Inspect the spring periodically for corrosion or deformation and replace it if elastic performance declines. When working with small mechanical parts, wear eye protection and follow standard workshop safety procedures.
