Thread ring gauge M12 x 1.5 mm — hardened gauge steel, DIN 13 (6g) — Metav IndustryLine

A thread ring gauge M12 x 1.5 mm designed for quick, accurate checking of metric ISO fine internal threads in production and inspection environments

• Hardened gauge-steel construction
• Conforms to DIN 13, tolerance class 6g
• For metric ISO fine threads M12 x 1.5

Precision where it matters: consistent acceptance testing

The ring is manufactured from hardened gauge steel, which maintains dimensional stability under repeated handling and resists wear during serial checks. That material choice, combined with manufacturing to DIN 13 and a 6g tolerance class, ensures the component functions as a reliable go gauge for metric ISO fine threads. For production lines, this translates into fewer false rejects and faster cycle times in the inspection stage, because measurements are standardised and immediately comparable across shifts and machines.

Practical benefits for the workshop and production floor

As a dedicated verification tool, the gauge removes ambiguity from pass/fail decisions: a precise fit confirms thread conformity, while the inability to engage signals non-conformance. The compact, single-piece design reduces handling complexity and shortens inspection routines; typical applications include first-article inspection, incoming goods checks and batch sampling. The robust construction delivers long service life, lowering the total cost of ownership compared with ad hoc measurement methods and frequent replacements.

Traceability and integration into quality workflows

Although primarily a tactile verification device, the ring gauge supports traceable quality procedures by supplying repeatable, standards-based checks that can be recorded in inspection reports. The simple go/no-go principle accelerates operator training and reduces interpretation errors. Where documented proof is required, the gauge’s compliance with established thread standards provides a clear audit trail for audits and supplier control, supporting consistent output and customer confidence.

FAQ

Is this ring gauge suitable for fine metric threads only?
The ring gauge is designed specifically for metric ISO fine threads with the M12 x 1.5 specification and is manufactured to match that application.

What does the 6g specification mean for inspection?
The 6g designation refers to the tolerance class according to the thread standard; it defines the acceptable clearance and ensures the gauge represents the intended fit for the internal thread being tested.

How should the gauge be used during routine checks?
Use the ring gauge as a go/no-go acceptance tool: the gauge should assemble smoothly onto the workpiece if the internal thread meets the specified limit; resistance or jamming indicates non-conformance.
