Setting ring 300 mm — hardened gauge steel (Metav IndustryLine)

The Setting ring 300 mm — hardened gauge steel is a precision ring gauge designed for internal diameter verification and master‑gauge applications in metrology laboratories and workshop inspection.

• Hardened, lapped gauge steel surface
• Certified to DIN 2250 / DIN 286
• Form C profile for internal checks
• Robust 20.8 kg construction

Reduce rejects with traceable dimensional control

The hardened and lapped surface guarantees stable contact conditions and minimal surface deformation, which directly improves repeatability in comparative measurements. Conformity with DIN 2250 and DIN 286 in JS4 tolerance provides a clear reference level for inspection processes and calibration chains. Using a purpose‑made ring gauge minimises subjective variation from hand tools, so production control becomes more reliable and measurable.

Built for repeatable, heavy‑duty inspection tasks

A substantial mass and the choice of gauge steel ensure thermal and mechanical stability during routine use; the weight contributes to consistent seating in fixtures and prevents light displacement when performing comparative checks. The Form C profile is tailored for internal diameter verification, offering a clear seating surface for cutters, mandrels and internal micrometers. This construction lowers the need for frequent rechecks and extends intervals between maintenance cycles.

Easy integration into quality workflows

The ring is suitable as a master reference for incoming inspection, process control and tool setting. Marked identification and the included article data support inventory and traceability within laboratory information systems; the unit functions well alongside calipers, internal micrometers and comparator setups. For procurement and repeat ordering the clear SKU and GTIN simplify stocking and document control in regulated environments.
