Reject (No‑go) thread plug gauge M120×4 — right‑hand, hardened gauge steel (Metav IndustryLine)

Reject (No‑go) thread plug gauge M120×4 designed for swift verification of metric ISO fine internal threads in production and inspection environments

• No‑go verification for M120×4 metric fine threads
• Hardened gauge steel for durable service life
• Supplied with calibration certificate
• Compliant with DIN 13, tolerance class 6H

Ensure only conforming threads reach assembly

A dedicated no‑go plug provides an unequivocal pass/fail decision during incoming inspection and in‑process checks. By failing threads that exceed the maximum material condition, the gauge prevents assembly faults and downstream rework. The combination of clearly defined geometry and the DIN 13, 6H tolerance basis delivers objective, repeatable results that fit documented quality procedures and reduce costly ambiguity in acceptance criteria.

Built to resist wear and keep tolerances

Manufactured from hardened gauge steel, the plug is dimensionally stable under repeated use and resists the abrasion typical in high‑volume inspection loops. The substantial mass (approx. 2.2 kg) reflects a robust design that helps preserve thread form and gauge integrity over long inspection runs. The right‑hand M120×4 profile is machined to provide a decisive seating condition: if the plug cannot be fully engaged, the thread exceeds the allowable size and is marked for rejection, preserving product reliability.

Traceable calibration for audit readiness

The tool is supplied with a calibration certificate, confirming measurement traceability and supporting quality audits and production records. This documentation simplifies integration into ISO‑aligned inspection plans and enables traceable monitoring of gauge condition over time. The gauge’s clear, single‑function design streamlines operator instructions and reduces the potential for misinterpretation during routine checks.

Practical use and workshop integration

The plug is intended for systematic checks of metric ISO fine internal threads in machining, fabrication and quality control environments. It functions as part of a straightforward acceptance workflow: a correct seat indicates conformance within the specified tolerance band, while a firm refusal to engage signifies an out‑of‑tolerance condition requiring corrective action. The gauge’s hardened construction and standardised form make it suitable for repeated cyclic use in production lines and inspection benches.

FAQ

What does "no‑go" or "reject" mean for this plug gauge?
The no‑go (reject) plug gauge is intended to detect threads that are oversize or otherwise out of the allowed tolerance band; if the plug does not fully engage, the part is rejected. The Reject (No‑go) thread plug gauge M120×4 provides this clear binary check for metric ISO fine internal threads.

Is a calibration certificate included with the gauge?
Yes, the plug gauge is supplied with a calibration certificate that documents traceability and measurement conformity, supporting audit requirements and quality records for the Metav IndustryLine Reject (No‑go) thread plug gauge M120×4.

What material is the gauge made from and why does that matter?
The gauge is made from hardened gauge steel, chosen for its wear resistance and dimensional stability; these properties preserve the plug’s geometry under repeated use and maintain consistent rejection thresholds.

For which standard and tolerance class is this gauge suitable?
The tool is manufactured to the DIN 13 specification and corresponds to tolerance class 6H, making it suitable for verifying metric ISO fine internal threads produced to that standard.

Can this plug be used on left‑hand threads?
This specific item is produced for right‑hand threads in the M120×4 form; left‑hand applications require a corresponding left‑hand gauge produced to the same dimensions and tolerance class.
