Setting ring 100 mm (gauge ring) – hardened gauge steel, DIN 2250 JS 3

Setting ring 100 mm for precision setting and verification of internal gauges and measurement equipment in workshops and inspection rooms.

• Hardened, lapped gauge steel construction
• DIN 2250 / DIN 286 tolerance JS 3
• Diameter 100 mm, Form C geometry
• Robust 2.3 kg mass for measurement stability

Reliable reference for workshop and inspection use

The Setting ring 100 mm is engineered as a stable reference for setting and checking internal measuring instruments. With a nominal diameter of 100 mm and compliance with DIN 2250, the ring provides a defined datum that simplifies transfer of dimensional standards across tools and setups. The clear normative specification helps integrate the ring into QA routines where traceable, repeatable references are required.

Material and finish that minimise wear and error

Manufactured from hardened gauge steel and delivered with a lapped finish, this gauge ring resists surface degradation and preserves form accuracy under frequent handling. The lapping process reduces micro-roughness, which lowers measurement scatter when mating gauges or styli are applied. The material selection and finishing approach therefore reduce long-term maintenance and protect measurement certainty.

Norm conformity for traceable tolerances

Designed to meet DIN 2250 and DIN 286, with tolerance class JS 3, the ring facilitates documented conformity checks and acceptance testing. These standards define the permissible deviation band, enabling users to rely on the ring as a reference within calibrated inspection chains. Such normative alignment supports quality control regimes and helps to demonstrate process capability during audits.

Stable mass and form for reproducible seating

At 2.3 kg, the ring offers sufficient mass to avoid displacement during routine handling, improving the repeatability of setting operations. The Form C profile ensures predictable contact geometry when gauging instruments are introduced, reducing operator-induced variation and enhancing the precision of comparative measurements.

Practical handling and integration into workflows

The ring’s compact size and clearly specified geometry make it straightforward to store and deploy on inspection benches or in gauge sets. The robust construction allows frequent use without rapid wear, and the normative documentation simplifies inventory classification in toolrooms and calibration labs. Use the ring as a primary reference for calibrating internal micrometres, bore gauges and comparative tests.

Proven sourcing and suitability for industry use

As part of the Metav IndustryLine range the ring is intended for industrial and workshop use where durable, standards-compliant gauge equipment is required. The combination of normative conformity, hardened and lapped material and a stable mass makes this component a pragmatic choice for quality-focused shops and inspection departments that require long-term reproducibility.
