Setting ring 20 mm — Gauge ring, hardened and lapped (DIN 2250) — Metav IndustryLine

Setting ring 20 mm is a precision gauge ring intended as a stable reference for plug gauges, setting tasks and inspection work under workshop and production conditions.

• Hardened and lapped gauge steel
• Conforms to DIN 2250 / DIN 286, JS 3
• Form C profile for standard applications

Reliable reference for dimensional control

The setting ring is manufactured to the tolerance class JS 3 under DIN 2250 and DIN 286, offering a consistent nominal diameter of 20 mm that serves as a baseline for go/no‑go checks and tool setting. Such conformity means the component can be incorporated into quality plans as a traceable reference, reducing uncertainty in process checks. Using a standardised reference ring simplifies transfer of measurements between machines and inspection stations and supports routine verification steps in production.

Durable design that preserves accuracy

Constructed from gauge steel, the ring is hardened and lapped to deliver a wear‑resistant bearing surface with stable contact geometry. The hardened substrate reduces plastic deformation under repeated engagement, while the lapped finish minimises surface asperities that could shift measured outcomes. These material and finishing choices translate into fewer replacements, less downtime and a longer service life for the reference tool—advantages that matter in continuous manufacturing environments where repeatability is essential.

Practical handling and traceable identification

The Form C profile provides a widely used geometry for easy seating with cylindrical gauges and fixtures, facilitating quick and reproducible engagement during inspection or setting routines. Clear identification is provided by the manufacturer SKU M313.020 and GTIN 4054469120584, which aids inventory and procurement workflows. The ring's design and labelling support straightforward integration into existing gauge sets and inspection procedures, helping to maintain process control with minimal adaptation. Metav’s role as a European quality filter underpins consistent supply and documentation for industrial users.
