Käfer Measuring Insert – 20 mm flat contact, M2.5 for dial indicators

The Käfer Measuring Insert 20 mm flat M2.5 is a steel measuring contact intended for dial indicators, providing a stable, repeatable contact surface for quality control and workshop metrology.

• 20 mm flat measuring face
• M2.5 thread for dial indicators
• Made from steel

Precise contact geometry for consistent measurement results

The flat 20 mm contact face provides a defined bearing area that reduces point-loading and improves measurement repeatability compared with smaller tips. A consistent contact geometry helps to minimise measurement scatter when comparing parts or checking runout; this leads to faster decision cycles on the shop floor and fewer re-measurements. The flat contact is especially suitable for planar or slightly curved surfaces where a larger contact area avoids local deformation.

Robust material and simple mounting for reliable use

Manufactured in steel, the measuring contact offers mechanical durability for regular use in a shop environment. The integrated M2.5 thread is compatible with common dial indicator mounting systems, enabling rapid replacement or exchange with standard holders. The choice of steel balances wear resistance and ease of machining, so routine inspection or replacement remains straightforward without special tools.

Suits inspection tasks in workshop and lab workflows

Designed as a compact measuring accessory, the insert supports tasks in incoming inspection, process control and assembly checks. By fitting established dial indicators, the component integrates into existing metrology setups with minimal adaptation, helping to keep throughput high and calibration procedures consistent. The accessory’s simple geometry also simplifies visual inspection of the contact face before critical checks.

Practical considerations and benefits for procurement

Selecting a standardised insert such as this reduces variant complexity for tooling cupboards and spares lists. The plain contact face minimises fixturing effort for shallow features and fast comparative measurements. Where interchangeability and uptime matter, the use of a standard M2.5 mount and a durable steel body supports efficient stock management and dependable service life in production environments.

FAQ

What mounting thread is used for this measuring insert?
The insert uses an M2.5 thread, which is a common standard for dial indicator contacts and compatible holders.

Which contact diameter does the insert provide?
The contact face has a 20 mm diameter for a broad, stable bearing area suitable for planar surfaces.

Is the measuring insert suitable for continuous workshop use?
The steel construction offers mechanical robustness for routine inspection tasks and regular shop-floor handling.

Can the flat face be used on curved surfaces?
The flat face is best for planar or gently curved surfaces; for highly contoured parts a smaller-radius contact tip is recommended.

Is the insert compatible with all dial indicators?
The insert is intended for dial indicators that accept an M2.5 threaded contact; compatibility should be confirmed with the indicator’s mounting specifications.
