Measuring contact insert, Ø 10 mm — convex R15, M2.5 thread (Käfer)

A measuring contact insert Ø 10 mm, convex R15, M2.5 designed for secure, repeatable contact with dial indicators in precision workshops and inspection stations.

• Convex contact R15 for stable engagement
• Threaded M2.5 for secure attachment
• Solid steel body for wear resistance
• Compatible with dial indicators for precision checks

Consistent contact geometry for reliable results

The convex contact geometry, featuring a radius of 15 mm (R15) and a contact diameter of Ø 10 mm, provides a defined contact point that reduces measurement variability. In production environments where cycle-to-cycle consistency matters, the shaped contact face minimises point loading and helps maintain repeatability when used with standard dial indicators. The geometry is explained so that users unfamiliar with contact-tip theory understand that a convex face spreads contact over a controlled area, which lowers local stress and gives more stable readings than a sharply pointed tip.

Robust steel construction that withstands workshop use

Manufactured in steel, the insert offers high wear resistance and dimensional stability under normal inspection loads. The choice of material means the part resists deformation during repeated contact, which preserves calibration intervals and reduces downtime for replacements. The item’s M2.5 thread ensures a secure mechanical connection to the indicator stem, so the contact tip remains firmly seated during tactile checks and light probing. Where traceable, repeatable measurements are required, a durable contact insert reduces the need for frequent replacements and keeps inspection routines efficient.

Practical compatibility and easy integration

Supplied as a compact measuring insert for dial indicators, the component integrates directly into common indicator stems via its M2.5 thread, eliminating the need for adapters in many setups. The simple geometry and standard thread size mean the insert can be used across a range of workshop and quality-control tasks, from component spot checks to fixture-based inspection. For applications where the workpiece surface varies, the convex tip assists in maintaining a stable point of contact even on slightly curved surfaces. If additional technical details are required to confirm suitability for a specific measurement task, Metav’s technical advisors are available to help with exact specifications and compatibility queries.

FAQ

What is the contact diameter of this measuring insert?
The measuring insert has a contact diameter of 10 mm and a convex face with R15, making it suitable for repeatable contact measurements with dial indicators.

Which thread is used to attach the tip to an indicator?
Attachment is via an M2.5 thread; the insert is designed for secure mounting on stems that accept M2.5 connections.

Is the insert suitable for heavy-duty or abrasive measurement tasks?
The insert is made from steel, offering good wear resistance for normal inspection work; for highly abrasive or specialised environments, consult Metav for recommendations.

Can this insert be used on curved workpiece surfaces?
Yes — the convex R15 contact geometry helps maintain stable engagement on slightly curved or uneven surfaces when used with a dial indicator.
