Thread Ring Gauge GO M90 x 4.0 — Right-hand, DIN 13 (6g) — Metav IndustryLine

The Thread Ring Gauge GO M90 x 4.0 is a right-hand GO ring gauge designed to check metric ISO fine threads to DIN 13 (6g) in production, incoming inspection and laboratory settings

• GO ring for metric ISO fine threads
• Hardened gauge steel for long service life
• Includes calibration certificate
• Conforms to DIN 13 tolerance 6g

Ensure process reliability with traceable GO checking

The Thread Ring Gauge GO M90 x 4.0 provides a fast, objective pass/fail check that reduces inspection time and eliminates subjective judgement. Built from hardened gauge steel, the ring resists wear and maintains form accuracy over many cycles, which preserves the thread limit for longer and reduces rework. Conformance to DIN 13 (6g) offers a recognised tolerance class for fine metric threads, enabling straightforward acceptance criteria in production control and supplier inspection. The GO-only topology is ideal where a definitive acceptance check is required at speed.

Built-in traceability and quality assurance for audit-ready inspection

Delivery includes a calibration certificate, ensuring documented traceability and simplified quality records for internal audits. Calibration documentation supports consistent measurement outcomes and helps integrate the gauge into quality-management processes. The combination of a GO check and certified calibration reduces the need for repeated crossover checks, supporting lean inspection routines while maintaining compliance with internal and customer standards.

Practical handling, compatibility and long-term value

The right-hand metric construction suits typical fastener production and verification workflows and integrates easily with established inspection benches. The compact, robust design offers straightforward handling during GO trials and is compatible with standard thread plug gauge storage and protection practices. With a stable material choice and certified calibration, the gauge fosters confidence in routine sampling and incoming inspection, helping to prevent assembly issues caused by out-of-spec threads.

FAQ

What does the GO designation mean for this thread ring gauge? The GO designation indicates a limit gauge that verifies whether an external thread fits within the maximum material limit; the Thread Ring Gauge GO M90 x 4.0 (Metav IndustryLine, SKU M315.790.9) performs this single, decisive acceptance check.

Is a calibration document included with delivery? Yes, the gauge is supplied with a calibration certificate, which documents the measurement state and supports traceability for quality records with the Metav IndustryLine thread ring gauge.

Which tolerance and standard does the gauge follow? The ring adheres to DIN 13 with tolerance class 6g, making it suitable for metric ISO fine-thread acceptance where that standard is specified.

Can the gauge be used for left-hand threads? This particular gauge is right-hand; left-hand checks require a corresponding left-hand ring. The current item is specifically a right-hand GO ring for M90 x 4.0 threads.

How should the ring be maintained to preserve accuracy? Store the ring in a dry, protected case and avoid impact or contamination; periodic recalibration and gentle cleaning will maintain performance of the hardened gauge steel ring.
