Setting ring 40 mm – hardened gauge steel, DIN 2250 (Metav IndustryLine)

The Setting ring 40 mm is a precision gauge for setting and checking diameters in toolrooms and inspection tasks, designed to the DIN 2250 and DIN 286 standards with JS 3 tolerance.

• Hardened gauge steel, lapped surface
• DIN 2250 & DIN 286, JS 3 tolerance
• Precise 40 mm diameter
• Compact Form C geometry

Precision where setup errors are costly

The compact ring serves as a reference diameter for adjusting mandrels, checking bore gauges and calibrating inspection fixtures, delivering a reliable mechanical standard for routine quality control. Made from hardened, lapped gauge steel, the component provides a true running surface and low local deformation under clamping. Conformity to DIN 2250 and DIN 286 in tolerance class JS 3 gives a clear, verifiable accuracy class that speeds decision‑making on the shop floor and reduces rework.

Robust shape for repeatable measurement

The Form C profile concentrates stiffness where it matters, permitting secure support in fixtures without introducing measurement artefacts. Its compact 40 mm diameter makes it easy to handle while retaining the cross‑sectional rigidity required for short‑range reference work. The lapped finish ensures consistent contact conditions for plug gauges and inside measuring instruments, improving repeatability and reducing scatter in consecutive measurements.

Designed for the workshop and inspection bay

As a routine calibration and setup tool, the ring integrates into daily workflows: it streamlines gauge setting, shortens machine changeover and provides a stable master for comparative checks. Backed by Metav IndustryLine’s quality screening and supply from Metav Werkzeuge, the product supports dependable procurement and traceable equipment lists for workshops and quality departments. The combination of standard conformity and robust manufacture provides both operational efficiency and long‑term reliability.

FAQ

What tolerance class does the ring meet? The setting ring complies with DIN 2250 and DIN 286 and is manufactured to tolerance class JS 3, providing a defined accuracy level for routine setting and checking tasks.

Which material is used for the reference surface? The reference is produced from hardened, lapped gauge steel, offering a durable and low‑deformation contact surface suitable for frequent use.

Can this ring be used for setting plug gauges and mandrels? Yes, the ring is intended as a reference for setting plug gauges, mandrels and for comparative checks in the workshop or inspection bay.

What does Form C mean for handling and fixturing? Form C indicates a compact, stiff profile that improves fixture support and reduces measurement distortion when the ring is clamped or located against a datum.

Is the product suitable for small‑component inspection in toolrooms? Its 40 mm diameter and stable geometry make it well suited for toolroom use and short‑range inspection tasks, where compact precision masters are required.
