Extension rod L 10 mm for dial indicators — Käfer

The Extension rod L 10 mm is a precision accessory for adapting dial indicators, extending gauge reach for tight or recessed measuring points while preserving contact geometry.

*10 mm extension length
*Measuring pin Ø 4 mm
*Designed for dial indicators
*Single-piece, precision ground

Reach confined measuring points with reliable geometry

The compact 10 mm extension increases the effective reach of a dial indicator without compromising alignment, enabling measurements in narrow bores or recessed features. The rigid single-piece construction preserves the original contact angle and repeatability, which is critical when transferring comparative measurements across multiple workpieces. For workshop workflows that require consistent readings, the short extension minimises added lever arm effects and helps maintain the original gauge calibration.

Precise contact through a Ø 4 mm measuring pin

A measuring pin Ø 4 mm provides a defined contact area for fine features and ensures stable engagement on cylindrical or small flat surfaces. The defined pin diameter reduces lateral play and supports reproducible deflection of the indicator’s probe. In plain terms, the accessory converts limited-access points into measurable positions while keeping measurement noise low and improving the reliability of comparative checks.

Simple adaptation and practical workshop benefits

Supplied as an extension piece for dial indicators, the component integrates smoothly into existing metrology setups and requires no additional fixtures. The concise geometry and standard pin diameter mean the part is suitable for a broad range of indicators that accept a 4 mm contact stud. This straightforward compatibility shortens setup time and supports higher throughput in inspection routines while preserving the precision expected in small-batch production and repair work.

FAQ

What does the extension piece change on a dial indicator?
The extension piece increases gauge reach by 10 mm while keeping the contact geometry defined by the Ø 4 mm measuring pin, enabling measurements in recessed or narrow areas.

Is the Ø 4 mm pin suitable for small bore measurements?
Yes, the Ø 4 mm contact pin provides a small, defined contact area that is appropriate for cylindrical bores and tight features when combined with a compatible indicator.

Can the extension be used with any dial indicator?
Compatibility depends on the indicator’s contact stud interface; the extension is intended for indicators accepting a 4 mm contact pin—check the indicator’s mounting standard for confirmation.

Will the extension affect measurement repeatability?
When correctly mounted, the short 10 mm extension minimises lever effects and preserves repeatability by maintaining rigid contact geometry.
