M313.072 setting ring gauge 72 mm — hardened & lapped (Metav IndustryLine)

The M313.072 setting ring gauge is a Form C ring gauge intended for precision setting and verification of external diameters and calibration tasks in toolrooms and inspection benches.

• Form C ring gauge, DIN 2250/286 compliant
• Hardened and lapped gauge steel finish
• JS3 tolerance for accurate fits
• Suited to workshop and inspection use

Precision where measurement matters

The setting ring is manufactured from gauge steel, hardened and lapped, providing a wear‑resistant measuring surface that preserves dimensional integrity over repeated use. Compliance with DIN 2250 and DIN 286 together with a JS3 tolerance class ensures that the component serves as a reliable reference for setting and checking gauges, micrometres and calibration fixtures. The stabilized surface finish reduces measurement scatter and supports consistent set‑ups across production runs, contributing to traceable process control.

Practical benefits for workshop and inspection

A ring of this specification simplifies routine calibration and go/no‑go verification tasks; its Form C design permits straightforward mounting and handling on benches and in jigs. The lapped bore yields low surface roughness, which reduces wear on mating parts and maintains fit accuracy. As a result, inspection cycles can be shortened and instrument downtime minimised. The combination of robust material treatment and close tolerance class benefits workshops that require reliable repeatability rather than frequent replacements.

Handling, maintenance and integration

Routine maintenance consists of gentle cleaning and corrosion protection; avoid abrasive contact with the measuring diameter to preserve the lapped finish. The ring integrates easily into existing calibration routines and can be used as a reference during setting of external gauges or as a control standard in incoming inspection. Proper storage, ideally in a protective sleeve or rack, helps to maintain the gauge’s reference quality and extends service life, supporting a lower total cost of ownership through fewer replacements.

Quality assurance and traceability

Manufactured to recognised metrological standards, the gauge supports documented quality processes and helps meet internal and external inspection requirements. The conformity to DIN standards and the tight JS tolerance provide an objective basis for acceptance criteria in production and quality assurance tasks. Where full calibration documentation is required, Metav can advise on suitable calibration services and traceability options to match laboratory or workshop needs.
