Extended Product Information

FAQs

What type of circlips are these pliers designed for?

These pliers are specifically designed for internal circlips that fit onto shafts with a diameter ranging from 10mm to 25mm.

What does 'DIN ISO 5254A' specification mean?

This specification denotes a German and international standard for circlip pliers, ensuring a certain level of quality, design, and performance.

How do the spring steel tips differ from standard tips?

The inserted cold-drawn spring steel tips are significantly more durable and resilient, offering up to 10 times longer service life compared to conventional turned tips.

Can I use these pliers for external circlips?

No, these pliers are designed exclusively for internal circlips. Knipex offers different models for external circlip applications.

What is the advantage of the slim head style?

The slim head style allows the pliers to access and work in confined spaces where larger or bulkier tools would not fit.

How do I clean and maintain the pliers?

Wipe clean with a dry cloth after use and apply a light machine oil to the screw joint periodically. Store in a dry place.

What is the purpose of the overexpansion guard?

The overexpansion guard prevents the circlip from being stretched beyond its elastic limit during installation, reducing the risk of distortion or breakage.

Troubleshooting

Pliers feel stiff or difficult to operate.

Apply a small amount of machine oil to the bolted screw joint and work the handles back and forth to distribute the lubricant. Ensure no debris is lodged in the joint.

Tips do not grip the circlip securely.

Verify that the circlip size and type are compatible with the pliers' capacity (10-25mm shaft diameter, 1.3mm tip diameter). Ensure the tips are clean and not worn or damaged. Check the bolted joint for excessive play.

Circlips are getting distorted during use.

Ensure the overexpansion guard is functioning correctly and that you are not applying excessive force. The large contact faces on the tips should prevent distortion if used properly within the specified circlip size range.

Setup, Compatibility & Care

Setup: These pliers are ready for immediate use out of the box. No assembly or initial setup is required.

Compatibility: Specifically designed for internal circlips with shaft diameters between 10mm and 25mm, conforming to DIN ISO 5254A standards. They are compatible with circlips designed for these shaft sizes.

Care: To maintain optimal performance and longevity:

  1. Cleaning: After each use, wipe the pliers clean with a dry, lint-free cloth to remove any debris or lubricant.
  2. Lubrication: Periodically apply a light coating of machine oil to the screw joint to ensure smooth operation and prevent rust.
  3. Storage: Store the pliers in a dry environment, preferably in a tool case or pouch, to protect the tips from damage and corrosion.
  4. Avoid Misuse: Do not use these pliers for tasks they are not designed for, such as cutting wire or general gripping, as this can damage the precision tips.
