Setting ring M313.038 — 38 mm, Form C, hardened gauge steel (Metav IndustryLine)

A Setting ring M313.038 engineered as a compact, traceable gauge for accurate setting and comparative checks in workshop and inspection environments.

• Setting ring 38 mm, Form C
• Conforms to DIN 2250 and DIN 286 JS 3
• Hardened, lapped gauge steel

Reliable standards for fast, repeatable setups

The ring is manufactured to meet DIN 2250 and DIN 286 with tolerance class JS 3, ensuring consistent interchangeability when used as a reference in production and inspection. This conformity reduces setup time and the need for repeated adjustments because the nominal diameter is produced within defined statistical limits. The combination of standardisation and a clear tolerance class delivers a measurable advantage in process control and makes the component suitable as a workshop master for go/no-go or comparative gauging.

Wear resistance that keeps tolerances over time

Constructed from gauge steel, the component is hardened and lapped, which improves surface stability and lowers running-in wear during repeated contact. The lapping process refines the contact surfaces to reduce local abrasion and micro‑deformation, so dimensional accuracy is maintained over many cycles. For users requiring a robust reference device, this material and finishing approach translates into fewer replacements, less downtime and more predictable measurement behaviour in daily operations.

Compact profile designed for practical integration

The Form C design offers a compact outer profile that eases handling and placement in fixtures or set-up aids, while the 38 mm nominal diameter fits common shaft and plug-gauge routines. As a setting device, the ring provides a straightforward means to transfer a known dimension into a machine or measurement chain, supporting quicker alignment and improved repeatability in assembly, turning or inspection tasks. Its geometry and finish make it a pragmatic choice for use as a workshop reference when accuracy and ease of use matter.
