Thread plug gauge NO‑GO M68 x 3.0 — Metric ISO fine thread, right‑hand, DIN 13 (6H) — Metav IndustryLine

The Thread plug gauge NO‑GO M68 x 3.0 is a hardened inspection gauge for verifying metric ISO fine internal threads (right‑hand), designed for use in production control and final inspection.

• Hardened gauge steel construction
• DIN 13 (6H) tolerance class
• Supplied with calibration certificate

Clear rejection when tolerance must be enforced

The NO‑GO plug gauge serves as a definitive go/no‑go control for internal threads: if the NO‑GO entry is accepted, the thread falls outside the permitted limits defined by DIN 13 (6H) and must be rejected. This straightforward mechanical check removes ambiguity from pass/fail decisions and speeds inspection routines on the shopfloor. By relying on a hard gauge rather than subjective measurement chains, process stability is improved and non‑conforming parts are identified at the earliest stage.

Durable construction for consistent repeatability

Manufactured from hardened gauge steel, the gauge resists wear and preserves its functional limits over repeated cycles, which supports reproducible inspections and reduces the frequency of replacement. The right‑hand configuration and thread form match metric ISO fine profiles for the M68 × 3.0 size, providing a robust contact geometry that resists deformation. A stable, physical comparator such as this is an efficient addition to in‑line gauging stations and manual quality benches where repeatability and low maintenance are priorities.

Traceable calibration for quality assurance

The tool is supplied with a calibration certificate, ensuring traceability of the inspection limit back to a recognised measurement event. This supports internal quality procedures and audits by documenting that the gauge was checked prior to delivery. Where recordable calibration is required for incoming tooling, the enclosed certificate enables immediate integration into inspection schedules without delay.

Practical benefits for production and QA teams

Using a dedicated NO‑GO plug gauge reduces measurement time compared with full profile inspection and simplifies operator training: the physical pass/fail principle is intuitive and limits interpretation errors. The compact, single‑purpose design helps maintain bench space and allows fast sampling across batches, which in turn helps maintain throughput while upholding component integrity. For routine monitoring of thread quality in machining or assembly, such a gauge is a cost‑effective tool to protect downstream processes from rejected parts.

FAQ

What does NO‑GO mean for this plug gauge?
The NO‑GO indication for the Thread plug gauge NO‑GO M68 x 3.0 means the gauge is designed to detect threads that exceed the maximum material condition; acceptance of the NO‑GO denotes a rejectable thread according to its DIN 13 (6H) limits.

Is a calibration certificate included with the gauge?
Yes, a calibration certificate is supplied with the Metav IndustryLine NO‑GO plug gauge, providing traceability and documentation for quality records.

Can this gauge be used for left‑hand threads?
This specific gauge is manufactured as a right‑hand thread plug gauge and is intended for inspection of right‑hand metric ISO fine threads sized M68 × 3.0.

What material is the gauge made from and why does that matter?
The gauge is made from hardened gauge steel, which provides wear resistance and dimensional stability so the limit condition remains reliable over repeated use.

How does this gauge relate to production quality control?
The plug gauge offers a quick, mechanical pass/fail check that accelerates sampling and reduces interpretation errors in the quality workflow; the NO‑GO function helps prevent out‑of‑tolerance threads from progressing further in production.
