Limit plug gauge M314.040 — 40.0 mm, DIN 2245 · H7 · Metav IndustryLine

Limit plug gauge M314.040 is a hardened gauge‑steel go/no‑go plug designed for quick, repeatable inspection of 40.0 mm bores to DIN 2245 with H7 tolerance.

• Hardened gauge steel construction
• DIN 2245 compliant geometry
• H7 tolerance for 40.0 mm bores

Reliable tolerance checking that speeds inspection

The M314.040 functions as a straightforward pass/no‑go verifier for cylindrical bores, enabling rapid acceptance or rejection of components directly on the shop floor. Manufactured to DIN 2245, the gauge ensures the correct basic profile for cylindrical bore checks; the H7 tolerance setting specifies the permissible size window for the part under test. By using a hardened gauge steel body, the tool maintains dimensional stability over repeated cycles, which reduces rework and keeps inspection throughput high. This combination of standardised geometry and robust material gives a clear, quantifiable basis for process control and traceability.

Durable construction for repeatable results and low maintenance

The hardened construction provides high wear resistance and consistent tactile feedback during checks, so the plug gauge retains its reference dimensions for longer service intervals. Repeatability benefits production control: fewer disagreements between operators and less reliance on time‑consuming measuring instruments for routine go/no‑go decisions. The compact, single‑piece design minimises handling variables and supports seamless integration into incoming inspection or in‑process check routines. Where faster decision making and reduced cycle time matter, this gauge offers an efficient balance of durability and operational simplicity.

Practical use, storage and quality assurance in the workshop

In practice, the plug gauge is used by inserting the “go” end into the bore to confirm the minimum acceptable diameter and checking the “no‑go” condition to verify the upper limit. The gauge is suited to production inspection, sample checks and fixture set‑up verification. For quality assurance records, the item can be included in traceable inspection plans and, if required, submitted for formal calibration to maintain documented accuracy. Metav’s service orientation and central European distribution ensure straightforward availability and a clear quality filter for replacement or calibration cycles, reinforcing confidence in routine measurement tasks.
