Combine the steel construction with a ball tip Ø 3 mm and an M2.5 mounting to ensure reliable contact transfer and consistent measurement results; order the measuring insert directly via Metav Werkzeuge or request compatibility advice from our consultants.

Käfer measuring insert — ball tip Ø 3 mm, M2.5 thread

The Käfer measuring insert is a steel, ball‑ended measuring insert designed for precise contact with dial indicators in workshop and inspection settings.

• Ball tip Ø 3 mm for precise contact
• Robust steel construction for durability
• M2.5 thread for standard dial indicators

High accuracy through minimal contact area

The ball tip with a Ø 3 mm diameter provides a defined contact geometry that reduces local deformation and supports high repeatability in comparative measurements. In practical terms, the rounded contact point converts surface irregularities into a stable point of reference, which is especially valuable when using dial indicators for run‑out, thickness or alignment checks. The compact geometry also helps to limit measurement uncertainty by reducing lateral forces during probing.

Built for workshop conditions and long service life

Manufactured from steel, the insert combines dimensional stability with good wear resistance under intermittent contact. The M2.5 thread ensures straightforward integration with common indicator stems and accessory adaptors found in inspection benches and portable measuring setups. Where frequent contact or abrasive surfaces are expected, the metallic construction maintains geometry for prolonged intervals, supporting dependable results and minimising replacement cycles.

Simple integration and clear benefits for procurement

As a dedicated measuring tip, the component facilitates fast replacement and standardisation across measurement chains, improving maintenance workflows and traceability of inspection routines. The straightforward mount and standardised thread size make inventory planning simpler for toolrooms and quality departments, while the defined ball tip geometry supports consistent contact pressure and reliable data capture during routine checks with analogue or digital readouts.
