M314.030 limit plug gauge — 30.0 mm, DIN 2245 H7 (Metav IndustryLine)

The M314.030 limit plug gauge is a purpose‑built go/no‑go inspection master for checking internal diameters to DIN 2245, suited to workshop and production‑line quality control.

• Hardened gauge steel construction
• Dimensional accuracy to DIN 2245 H7
• Compact, hand‑operated inspection gauge

Ensure repeatable diameter checks on the shop floor

The hardened gauge‑steel construction delivers dimensional stability and wear resistance, helping maintain measurement repeatability over many cycles. As a limit plug gauge to DIN 2245, the component provides a clear go/no‑go indication for internal bores at 30.0 mm, allowing quick decisions during process control. The simple mechanical check requires no power, which reduces setup time and enables immediate integration into in‑line inspection routines, minimising production interruptions while preserving throughput.

Built for durability and low maintenance

Thanks to hardened gauge steel and precise manufacturing to the H7 tolerance class, the instrument resists deformation and surface wear that can compromise results. This robustness translates into less frequent replacement and lower total cost of ownership for quality teams. The compact form supports one‑hand operation and easy handling at the point of measurement, while the gauge’s finish reduces snagging and facilitates straightforward cleaning between shifts.

Practical benefits for quality assurance workflows

A mechanical go/no‑go gauge provides an unambiguous pass/fail decision at the machine or assembly station, accelerating inspection throughput and reducing reliance on measurement interpretation. The tool acts as a rapid first‑line control to catch out‑of‑tolerance parts before they proceed to subsequent operations. Maintenance teams gain from the gauge’s predictable behaviour: when used according to routine inspection protocols, it assists in keeping process capability metrics stable and traceable.

Conforms to recognised standards for traceability

Manufactured to match DIN 2245 requirements, the gauge aligns with common European inspection standards used in machining and toolroom environments. Documentation and marking on the instrument support traceability within calibration and quality management systems, making it suitable for manufacturers that depend on consistent checking methods to uphold product integrity and regulatory compliance.

FAQ

What tolerance class does this gauge check to?
The gauge is produced for the H7 tolerance class in accordance with DIN 2245, delivering an unambiguous go/no‑go check for 30.0 mm bores.

Is the instrument suitable for continuous use in production?
Yes. The hardened gauge‑steel construction of the M314.030 limit plug gauge is designed for repetitive checks on the shop floor and offers resistance to wear under normal inspection cycles.

How is the gauge intended to be used in quality workflows?
Use the go/no‑go plug to verify whether internal diameters meet the DIN 2245 H7 requirement; it is intended as a fast in‑process control to prevent out‑of‑tolerance parts from advancing.

Does the gauge require calibration documentation?
The product is manufactured for traceable inspection routines; calibration and documentation options should be discussed with Metav Werkzeuge to match the purchaser’s quality‑management needs.

Which materials and applications are typical for this gauge?
This limit plug gauge is commonly applied in metalworking and component manufacturing where internal bore checks are required, particularly for parts produced on lathes, boring machines or as part of assembly verification.
