Limit plug gauge M314.020 — 20.0 mm H7, DIN 2245 (Metav IndustryLine)

The limit plug gauge M314.020 is designed for rapid, standards‑based verification of 20.0 mm bores in production and inspection environments.

• Hardened gauge steel construction
• DIN 2245 H7 tolerance for accurate checks
• Compact 20.0 mm diameter, 0.2 kg mass

Traceable conformity for reproducible bore decisions

The gauge is manufactured to DIN 2245 and sized to H7, providing a straightforward pass/fail result for nominal 20.0 mm bores. This standards‑based approach removes ambiguity from routine inspections: measuring personnel gain a clear acceptance criterion without complex calculations. Using a dedicated plug gauge reduces cycle time during batch inspection and supports consistent quality documentation, helping to keep production tolerances under control.

Robust material choice for extended service life

Constructed from hardened gauge steel, the tool resists wear from repeated seating inside nominal bores and maintains dimensional stability over many inspection cycles. The modest mass of 0.2 kg and the compact form factor make handling ergonomic for single‑operator checks while the hardened finish sustains accurate contact geometry. The combination of durable material and standardised manufacture contributes to lower lifecycle costs through reduced rework and fewer replacements.

Simple to use in shopfloor and inspection routines

As a limit plug gauge, operation is immediate: the gauge is seated in the bore to verify conformity to the H7 tolerance; a smooth fit indicates acceptance, while any interference signals an out‑of‑tolerance condition. The straightforward go/no‑go logic minimises training time and speeds up first‑article and in‑process checks. For traceability, the compact design integrates easily into inspection stations, supplying an objective decision step that complements micrometre and caliper measurements.

Practical placement in quality workflows

Well suited to machine shops, assembly lines and quality control benches, the gauge supports routine verification of mating components, housings and bores where a 20.0 mm nominal size is required. The tool aligns with a pragmatic quality regime: quick checks at the machine, final inspection before dispatch, or spot audits during production runs. As a Metav IndustryLine product, it arrives ready for immediate use within established metrology chains and is straightforward to store and handle between checks.

FAQ

What size of bore is this gauge intended to check?
The limit plug gauge M314.020 is made for inspection of 20.0 mm nominal bores and verifies conformity to the H7 tolerance class.

Which standard governs this plug gauge?
Manufacture and dimensions comply with DIN 2245; the Metav IndustryLine limit plug gauge M314.020 is produced accordingly.

What material is the gauge made from and why does that matter?
The gauge is manufactured from hardened gauge steel; this material preserves contact geometry and resists wear during repeated inspections.

How is the acceptance determined with this tool?
A smooth, unrestricted seating of the gauge into the bore confirms acceptance to H7, while any tightness indicates out‑of‑tolerance condition requiring further investigation.

Can the gauge be used on the shopfloor for routine checks?
Yes — the compact design and modest mass make the Metav IndustryLine plug gauge suitable for fast, repeatable checks at the machine or inspection bench.
