Measuring insert Ø 4.8 mm flat M2.5 (Käfer) — flat measuring insert for dial indicators, steel construction

A compact flat measuring insert designed for dial indicators, providing a small contact face and an M2.5 threaded shank for secure mounting in measurement fixtures and gauge holders.

• Flat measuring tip Ø 4.8 mm
• Threaded M2.5 for secure fit
• Made of steel for durability
• Suitable for dial indicators

Consistent contact geometry for repeatable results

The flat contact design ensures a defined measurement interface that reduces variability when checking flat surfaces or plug features. Thanks to the Ø 4.8 mm contact face and the short, threaded fixing, the component provides repeatability across successive measurements and helps to maintain a stable datum when used with dial gauges. The compact dimensions make it suitable for confined setups while preserving measurement reliability in routine inspection tasks.

Secure mounting and simple integration into fixtures

The M2.5 thread enables positive mechanical fixation into threaded gauge adapters or custom fixtures, eliminating micro-movement under load and improving measurement stability. The insert’s plain form minimises alignment errors during installation and the standardised thread size simplifies replacement or interchangeability in existing gauge systems. This supports efficient calibration cycles and reduces downtime caused by frequent adjustments.

Durable material choice for long-term use

Produced in steel, the insert offers wear resistance and dimensional integrity under regular contact loads typical for workshop metrology. The material selection balances hardness and toughness for sustained service life while maintaining the contact surface fidelity required for precision metrology. Where occasional reconditioning is needed, the simple geometry expedites maintenance without complex tooling.

Practical benefits for metrology and workshop environments

Supplied as a single unit in a compact package, the insert is an economical spare-part option for inspection benches and portable measuring rigs. Its straightforward design allows fast replacement and predictable performance, contributing to reliable process control and traceable inspection records. The combination of compact size, steel construction and standard thread supports both bench-top and shop-floor quality assurance routines.

FAQ

What applications suit this flat measuring insert? This flat measuring insert is intended for use with dial indicators to check flat surfaces, small grooves and repeat contact points where a compact Ø 4.8 mm contact face is advantageous.

Is the thread compatible with common gauge adaptors? The M2.5 thread is a standard fixing size; it fits typical threaded pockets and adapters designed for small measuring inserts and dial gauge accessories.

How does the steel material affect performance? Steel construction provides good wear resistance and dimensional stability under regular contact use, ensuring consistent measurement outcomes over time.

Can this insert be used on delicate or soft surfaces? The flat steel contact is best suited to hard or prepared surfaces; for delicate materials, consider using a protective pad or alternative contact tip designed for soft materials.

Is the insert supplied ready to fit or does it require machining? The component is supplied ready to mount; straightforward fixation via the M2.5 thread is all that is required for installation in compatible holders.
