Limit plug gauge M314.031 — 31.00 mm H7, DIN 2245 (Metav IndustryLine)

The Limit plug gauge M314.031 is a hardened gauge-steel go/no-go plug designed for quick verification of metric bores to DIN 2245 with an H7 tolerance, suitable for production and incoming inspection tasks.

• 31.00 mm nominal diameter H7
• Conforms to DIN 2245 tolerance standard
• Hardened gauge-steel for repeatable checks

Reliable in-line inspection that reduces rejects

The limit plug functions as a fast, unequivocal gauge for go/no-go assessment, enabling timely decisions on part acceptance. With a 31.00 mm nominal diameter and H7 tolerance, the tool supports standardised quality checks and helps to reduce downstream rework by catching out-of-tolerance bores at the first control stage. This contributes directly to improved throughput and lower scrap rates.

Robust construction for consistent measurements

Manufactured from hardened gauge steel, the gauge offers mechanical stability and wear resistance that preserve the calibrated fit over repeated cycles. The go/no-go design eliminates subjective judgement in pass/fail calls, which is particularly valuable on assembly lines and in high-volume inspection where consistency is essential for process reliability.

Standards compliance and traceable specification

Conformance to DIN 2245 ensures the gauge matches established geometry and tolerance conventions for plug gauges, making it compatible with typical metrology procedures and quality documentation. The clear designation of H7 tolerance provides a verifiable basis for conformity assessment and helps integrate the check into existing inspection plans or control charts.

Practical use and handling benefits

The compact limit plug simplifies handling during routine checks and can be used at the bench or inline without special fixtures. Its straightforward go/no-go indication speeds up sampling routines and supports lean-quality workflows, providing operators with quick, objective results that promote confidence in outgoing parts and reduce inspection time per component.

FAQ

What is the primary use of this plug gauge?
The limit plug gauge M314.031 is used for rapid go/no-go inspection of bores with a nominal size of 31.00 mm to verify conformity with DIN 2245 and H7 tolerance.

Which standard and tolerance does it check?
This gauge is manufactured to DIN 2245 and configured to the H7 tolerance class for metric bores.

What material is the gauge made from and why does it matter?
The tool is made from hardened gauge steel, which ensures wear resistance and dimensional stability for repeatable checks over time.

Is the gauge suitable for production-line sampling?
Yes, the go/no-go characteristic of this limit plug gauge makes it well suited for quick production sampling and in-line inspection routines.

Can the gauge be used with other nominal sizes?
The device is specific to a 31.00 mm nominal bore; for other sizes, corresponding limit plug gauges should be selected.
