Measuring pin Ø 1.5 mm L30 mm (M2.5) for dial indicators — KÄFER

A measuring pin Ø 1.5 mm L 30 mm (M2.5) is designed as a measuring insert for dial indicators, providing a compact, workshop-ready contact tip for repeatable dimensional checks

• Precision Ø 1.5 mm measuring tip
• Length 30 mm for extended reach
• Made from steel for durable contact
• Thread M2.5 for secure mounting

Accurate contact for repeatable readings

The compact measuring pin is engineered to deliver consistent contact geometry when used with dial indicators. The defined Ø 1.5 mm tip reduces point deformation and concentrates the contact area, which improves repeatability across multiple measurements. For metrology work where consistent probe contact is essential, the small tip diameter supports precise point contact on workpieces without excessive indentation, enabling reliable comparative measurements in inspection routines.

Robust material and simple mounting

Manufactured in steel, the insert combines everyday workshop durability with straightforward installation. The M2.5 thread provides a standardised mechanical interface, ensuring a tight fit in compatible indicator stems and holders. This design reduces play that can distort readings and simplifies replacement during routine maintenance. The solid-metal construction also ensures dimensional stability under typical workshop loads, contributing to long service life without the need for special handling.

Practical application in inspection and quality control

As a measuring insert for dial indicators, the component is particularly suited to fine positional checks, small-bore gauging and repeat measurements on turned or milled parts. The 30 mm length balances accessibility and control: it allows measurement in slightly recessed areas while maintaining stiffness to limit deflection. For production environments where frequent checks are performed, the insert serves as a reliable, easy-to-replace contact point for rapid inspection cycles.

Compatibility considerations and benefit explanation

Compatibility depends on the indicator’s stem and mounting configuration; the M2.5 thread is a common specification for small contact pins in metrology accessories. When paired with a calibrated dial indicator, the insert helps preserve instrument accuracy by providing a defined, wear-resistant contact surface. Choosing a standardised insert reduces downtime and inventory complexity, supporting efficient quality-control workflows in workshops and inspection benches.
