Metav IndustryLine Limit Plug Gauge M314.021 — Ø 21.0 mm (H7), DIN 2245

A Limit Plug Gauge M314.021 designed for straightforward verification of hole diameters to DIN 2245 tolerances in workshop and production environments.

• Hardened gauge steel construction
• Conforms to DIN 2245, H7 tolerance
• Ø 21.0 mm nominal diameter
• Suitable for go/no‑go hole checks

Faster inspection that protects throughput

A compact limit plug gauge enables rapid, binary assessment of hole acceptability, turning a previously time‑consuming measurement into an immediate decision. With a clearly defined H7 tolerance and a nominal diameter of Ø 21.0 mm, the gauge supports quick inline checks that help maintain production flow and reduce costly rework. The straightforward go/no‑go result shortens inspection time and fits naturally into a shop‑floor quality routine, supporting lean processes and predictable cycle times.

Proven standardisation for reliable interchangeability

Manufactured to DIN 2245, the gauge provides an objective reference for hole tolerances that is recognised across suppliers and inspection regimes. The standardised geometry means measurements are comparable between shifts and sites; traceability and auditability are therefore improved. Built from hardened gauge steel, the gauge resists wear and preserves dimensional integrity so that conformity to the specified tolerance band remains consistent over repeated use.

Robust design for everyday handling

The heat‑treated construction and precise finishing minimise surface damage during handling, which preserves the functional fit of the plug gauge in serial checks. The device is intended for practical use in production and workshop settings where repeatability matters: a durable gauge reduces the need for frequent replacement and ensures stable performance under normal operating conditions. As a single‑purpose inspection tool, the plug gauge offers predictable behaviour and low maintenance.

Integrating the gauge into quality routines

For quality managers and workshop supervisors, the main advantage is clear: a limit plug gauge delivers an efficient, evidence‑based pass/fail result for hole diameters. This tool complements dimensional measurement equipment by providing immediate verification at critical process steps. When used as part of an inspection plan, the gauge helps to prevent non‑conforming parts from progressing through assembly, thereby protecting downstream operations and customer satisfaction.
