Limit plug gauge 42.0 mm (DIN 2245 / H7) — Metav IndustryLine

The Limit plug gauge 42.0 mm (H7) is a compact, shop‑ready go/no‑go cylindrical gauge designed for quick acceptance testing and routine size control in production and inspection environments.

• Hardened gauge steel construction
• DIN 2245 tolerance H7
• Nominal diameter 42.0 mm

Consistent size control for routine inspection

This precision instrument supports fast verification of bore diameters by offering a clear go/no‑go decision at the point of measurement. Manufactured from hardened gauge steel, the gauge resists wear during repeated checks, which maintains the effective limit size over many cycles and reduces the need for frequent replacement. The adherence to DIN 2245 and the specified H7 class provides a recognised reference for conformity assessment and simplifies in‑process quality gates in machine shops and inspection benches.

Built for repeatability and low effort handling

A compact cylindrical design yields stable engagement in the bore and reduces wobble during manual checks, contributing to repeatable outcomes across operators. The instrument’s geometry and surface finish enable unmistakable tactile feedback on go/no‑go seating, turning a measurement decision into a fast, low‑skill operation. By removing ambiguity from acceptance testing, the gauge shortens inspection time and supports consistent throughput on the shop floor.

Rapid integration into quality workflows

As a traditional limit gauge, this item fits seamlessly into standard inspection routines and documentation. Its conformity with DIN 2245 facilitates direct use as an acceptance tool during final inspection or in‑process sampling, while the clear go/no‑go principle integrates easily with statistical process control points. The simple, binary result supports quick decision-making and reduces machine downtime caused by uncertain measurements.

Durable materials and clear specification for procurement

The use of gauge steel, hardened ensures long service life under normal usage, while the nominal size 42.0 mm and tolerance class H7 are stated explicitly for procurement and traceability. The compact specification aids stores and purchasing departments in stocking the correct reference item for routine checks, avoiding mismatches that lead to measurement disputes or production delays. The product’s SKU and standard reference support inventory management and documentation.

FAQ

What is this gauge intended for?
The limit plug gauge is intended for quick acceptance checks of internal diameters; the Metav IndustryLine plug gauge M314.042 provides a go/no‑go indication for a 42.0 mm bore under DIN 2245/H7.

How does the gauge indicate conformity?
Conformity is shown by the go/no‑go principle: the go end should enter the bore if within tolerance and the no‑go end should not; the plug gauge M314.042 is produced to the H7 class for unambiguous acceptance checks.

Is this instrument suitable for shop‑floor use?
Yes; the hardened gauge‑steel construction and compact form make the gauge suitable for repetitive checks on the shop floor where rapid, repeatable assessment is required.

Can this gauge be used for documentation in inspection reports?
The gauge’s compliance with DIN 2245 and clear nominal/tolerance marking supports its use as a recorded reference in inspection documentation and process control charts.
