Clamping holder, mounting Ø 4 + 8 H7 mm, shank 72 x 12 x 6 mm (Käfer)

The clamping holder, mounting Ø 4 + 8 H7 mm, shank 72 x 12 x 6 mm is designed to provide stable, repeatable fixation for lever-type test indicators in inspection and set-up tasks across workshop environments.

• H7 mounting bores Ø 4 and Ø 8 mm
• Robust shank 72 x 12 x 6 mm
• Suited for lever-type test indicators
• Precision ground clamping surfaces

Secure mounting for accurate indicator readings

The holder provides a defined H7 tolerance on both mounting bores, which ensures a tight, standardised fit for commonly used indicator stems with diameters of Ø 4 mm and Ø 8 mm. The H7 class denotes a fine manufacturing tolerance, producing minimal radial play and improving repeatability during measurements. By limiting movement at the interface, the fixture reduces reading scatter and supports reliable comparators and alignment checks in routine inspection work. This mechanical stability is especially valuable when multiple set-ups are required over a production shift.

Compact design that matches workshop workflows

With a 72 x 12 x 6 mm shank, the component occupies little space on magnetic bases, posts or bespoke holding fixtures while offering a firm grip where space is limited. The compact dimensions allow integration into existing test rigs or portable inspection assemblies without extensive modification. Compatibility with lever-type test indicators makes the holder a practical choice for bench checks, fixture calibration and rapid comparative measurements. The compact form factor also simplifies storage and handling when multiple holders are kept for different indicator types.

Operational benefits for inspection and set-up tasks

The holder’s precision ground clamping surfaces and clearly defined bore sizes reduce set-up times and lower the risk of misalignment, delivering tangible efficiency improvements in measurement routines. Standardised fits mean fewer bespoke adapters are needed, which shortens preparation cycles and contributes to a steadier throughput. Confidence in consistent fixturing supports better quality assurance reporting and helps maintain process control during small-batch production or prototype runs.

FAQ

What mounting diameters does the clamping holder accept?
The clamping holder accepts stems in Ø 4 mm and Ø 8 mm, each produced to an H7 tolerance for a secure fit.

Is the holder suitable for dial test indicators or lever-type indicators?
The design is intended for lever-type test indicators and similar feeler-style measuring instruments commonly used in workshop metrology.

How does the H7 tolerance affect measurement reliability?
An H7 tolerance reduces radial play between holder and indicator stem, improving repeatability and lowering measurement scatter during comparative checks.

Can the holder be integrated into existing fixtures and magnetic bases?
Yes, the compact 72 x 12 x 6 mm shank is dimensioned for straightforward integration into standard bases and bespoke holding systems.
