Käfer measurement insert — Ball probe Ø 3 mm, M2.5 thread (plastic)

A Käfer measurement insert is designed as a 3 mm ball-tip probe with M2.5 thread for use on dial indicators, providing gentle contact for delicate surfaces

• Ball-tip probe Ø 3 mm, length 6 mm
• Thread M2.5 for dial indicator mounting
• Plastic construction for gentle contact
• Precision insert for repeatable readings

Gentle contact for sensitive measurement surfaces

The ball-shaped probe head delivers consistent tactile contact while minimising surface marking on delicate parts. Built from plastic, the insert reduces the risk of abrasion and is particularly suitable for soft or polished materials where metal tips could cause damage. The small Ø 3 mm ball concentrates contact force into a predictable area, aiding stable probe-to-workpiece interaction and improving repeatability during comparative checks. For workshops and inspection benches requiring non-marring engagement, this design offers a practical blend of care and control.

Compact dimensions and robust mounting for tight setups

With a 6 mm effective length and an M2.5 thread, the probe insert integrates easily into tight indicator stems and accessory holders commonly used in precision measurement. The short profile reduces lever play and helps preserve the alignment of the measuring chain, which in turn supports precise indication transfer. The standard M2.5 interface ensures compatibility with many dial indicators and accessories, simplifying installation and replacement without the need for bespoke adaptors.

Repeatable readings that speed up inspection workflows

Engineered for stability, the ball-tip geometry and plastic construction deliver consistent contact conditions across repeated measurements. This predictability reduces scatter in comparative checks and supports faster decision-making on the shop floor. Where throughput and accuracy matter, the insert assists technicians in achieving uniform results with less adjustment time. The component’s simple form factor also makes it a low-maintenance option for routine use in assembly, QA sampling and first-article inspections.

Practical compatibility and workshop guidance

The insert is intended for use with dial indicators and related measuring heads where a small ball tip is required. Its plastic composition and ball form suit applications on fragile finishes and soft alloys alike. If additional technical details are required to confirm fitment with a specific indicator model, the Metav contact channels are available for clarification. For customers consolidating metrology supplies, this insert represents an economical, low-risk component to keep as part of a standard inspection kit.
