Setting ring gauge M313.165 — 165 mm master ring gauge, hardened and lapped (Metav IndustryLine)

The Setting ring gauge M313.165 serves as a durable, traceable master for internal dimensional control in production and inspection environments.

• Hardened and lapped gauge steel
• DIN 2250 / DIN 286, tolerance JS 3
• Form C profile
• 165 mm nominal diameter

Accurate master standard for inline quality control

The ring is manufactured from hardened and lapped gauge steel, delivering a wear-resistant contact surface that preserves the reference dimension over repeated use. Compliance with DIN 2250 and DIN 286 at tolerance JS 3 ensures the ring functions as a reliable master for setting internal gauges and verifying bore sizes, reducing measurement uncertainty and speeding up inspection cycles. As a stable calibration artefact, it supports consistent pass/fail decisions on the production line and helps to lower scrap rates.

Stable geometry for repeatable measurements

The Form C profile and substantial mass contribute to geometrical stability during handling and measurement, so readings remain repeatable across multiple operators and shifts. The lapped finish minimises surface irregularities that can affect contact geometry, while the overall construction resists deformation. This stability translates into fewer adjustments during routine checks and a more predictable process capability for medium and long production runs.

Designed for practical workshop integration

With its 165 mm nominal diameter and robust construction, the master ring integrates readily into inspection benches and gauge sets. The ring functions as a fixed reference for calibrating internal measuring equipment and can be used alongside plug and dial gauges to build a traceable control chain. For specialised setups or large-volume applications, the ring’s conformity to recognised standards simplifies documentation and audit processes, supporting quality management systems without adding administrative complexity.

FAQ

What tolerance does this ring meet?
The setting ring gauge M313.165 meets DIN 2250 and DIN 286 with tolerance JS 3, providing a clearly defined manufacturing and inspection limit.

What material is the master ring made from?
The M313.165 is manufactured from hardened and lapped gauge steel, chosen for dimensional stability and resistance to wear.

For which applications is this ring intended?
This master ring is intended as a traceable reference for internal gauge calibration, bore verification and workshop inspection routines in production and metrology stations.

How should the ring be handled to maintain accuracy?
Handle the master ring with clean gloves, store it in a dry, dust-free environment and avoid direct impacts; regular visual inspection and controlled storage prolong the lapped surface condition.

Can the M313.165 be used as a portable reference?
Its robust design and mass allow controlled use as a shop-floor master; however, transport should be performed in suitable packaging to avoid surface damage.
