Limit plug gauge M314.004 — 4.00 mm H7 inspection gauge (Metav IndustryLine)

A limit plug gauge M314.004 designed for fast go/no-go verification of 4.00 mm H7 bores in production control and incoming inspection.

• Limit plug gauge 4.00 mm H7 (DIN 2245)
• Hardened gauge steel for high wear resistance
• Fast go/no-go verification in production

Keep tolerances under control with standardised checks

The combination of DIN 2245 specification and H7 tolerance means this gauge provides a clear, standardised pass/fail decision for small bores. A properly specified limit gauge replaces time-consuming measurement routines with an immediate assessment: the part either accepts the “go” end or is stopped by the “no‑go” end. This approach reduces inspection time, simplifies production workflows and helps prevent costly rework by detecting out‑of‑tolerance bores at the point of manufacture. The design is tailored to frequent use where repeatability and unambiguous results are required.

Robust construction for repeatable performance

Made from hardened gauge steel, the inspection pin offers elevated wear resistance and dimensional stability under frequent handling. The compact mass (approx. 0.1 kg) and solid geometry keep deflection minimal during insertion, so readings remain consistent across many cycles. Such material choice is common for gauges intended for everyday shop‑floor use because it withstands abrasion and preserves the critical diameter over long service intervals. Regular visual checks and light lubrication will prolong service life and maintain reliable function for production control.

Simple to integrate into process control

The compact, single‑purpose format supports workflow efficiency: use the go/no-go characteristic for rapid inspection at stations, in fixture checks or at receiving. The clear pass/fail method makes operator training straightforward and reduces subjective interpretation of results. Supplied under the Metav IndustryLine designation M314.004, this inspection tool integrates smoothly into quality documentation systems where quick verification is required repeatedly rather than full dimensional measurement with calipers or gauges.

Confidence through a dedicated precision partner

Sourcing the gauge from Metav IndustryLine connects the tool to a broader service of stock, traceability and product range that helps streamline procurement. Metav’s focus on democratising precision and its extensive catalogue mean high‑accuracy tools are accessible to workshops and industrial buyers alike. The result is dependable availability and a single partner for complementary inspection equipment, simplifying supply chains and supporting consistent quality control across production.

FAQ

What tolerance class does this gauge check?
The limit plug gauge checks bore tolerance H7 in accordance with DIN 2245; the M314.004 provides a clear go/no‑go assessment for H7 fits.

Is the gauge suitable for production inspection?
Yes — the M314.004 is designed for fast pass/fail checks on the production line and for incoming inspection where rapid verification is required.

What material is the tool made from?
The inspection pin is manufactured from hardened gauge steel, chosen for wear resistance and dimensional stability under frequent use.

How should the gauge be stored and handled?
Store the gauge in a dry, clean environment, protect it from impacts and corrosive agents, and perform light maintenance such as cleaning and occasional lubrication to preserve the 4.00 mm measuring surface.

Can this gauge replace full dimensional measurement?
A limit plug gauge like this provides unambiguous pass/fail verification; it complements but does not substitute for full dimensional analysis when documented measurement traceability is required.
