Limit plug gauge M314.025 — 25.00 mm H7, DIN 2245, hardened gauge steel (Metav IndustryLine)

The Limit plug gauge M314.025 is a hardened, DIN 2245-compliant plug gauge designed for fast verification of 25.00 mm bores to H7 tolerance in production, inspection and incoming goods control.

*DIN 2245 standard for plug gauges *H7 tolerance for 25.00 mm verification *Hardened gauge steel, precision ground *Metav IndustryLine: workshop-ready accuracy

Consistent acceptance testing to lower scrap rates

The gauge is intended for swift, repeatable go/no-go checks that streamline inspection routines and reduce uncertainty on the shop floor. Made to the DIN 2245 specification and set for H7 verification at 25.00 mm, the instrument enables immediate decisions during batch runs and setup checks. Using a purpose-built limit plug for acceptance testing shortens cycle times compared with measurement on CMMs for routine pass/fail assessments, which helps to maintain throughput without sacrificing traceability.

Robust construction for long service life

Manufactured from hardened gauge steel and precision ground, the device is optimised for wear resistance and dimensional stability under repeated handling. The hardened surface and grinding process ensure that the functional diameters remain within tolerance for extended intervals, reducing the need for frequent regrinding or replacement. The solid construction supports reliable mating with standard bore seats and contributes to consistent tactile feedback during go/no-go verification.

Clear role in quality systems and traceability

Compliance with DIN 2245 places the gauge directly within established metrology regimes and simplifies documentation in inspection protocols. The clear design and standard tolerance class make the gauge suitable for inclusion in ISO-aligned quality procedures, offering a traceable method for conformity checks. Where process control relies on rapid discrimination between acceptable and non‑conforming parts, a standardised limit plug provides an objective, reproducible verdict that complements dimensional sampling plans.

Practical workshop use and application areas

This plug gauge is appropriate for machine shops, tool rooms and incoming goods inspection where round hole tolerances around 25 mm are frequent. Its uncomplicated go/no-go function supports fast cycle checks during set-up, first-piece inspection or production sampling. The device is particularly useful where interchangeability and straightforward evidence of conformity are required, such as in hydraulic component manufacture, bearing seat production or general mechanical assembly.
