Thread ring gauge GO M120 x 4.0 — metric ISO fine thread, right‑hand (Metav IndustryLine)

The Thread ring gauge GO M120 x 4.0 is a precision right‑hand ring gauge for fast verification of external metric ISO fine threads in production and incoming‑goods inspection.

• Includes calibration certificate
• Hardened gauge steel construction
• For metric ISO fine thread M120 x 4.0
• Conforms to DIN 13, tolerance 6g

Reliable acceptance checks to keep production flowing

The GO ring is designed for repeatable, tactile acceptance tests during series production. As a GO gauge, it verifies that external threads meet the lower limit of the tolerance band; if the ring fits onto a thread, the part passes the acceptance check. Made of hardened gauge steel, the ring resists wear and preserves dimensional stability over many cycles, which reduces scrap rates and minimises downtime. This direct pass/fail method is simple to integrate into assembly stations and quality control benches.

Traceable calibration for documented quality assurance

Delivered with a calibration certificate, the gauge is ready for use where documented traceability is required. The supplied certificate supports internal quality records and supplier audits, enabling straightforward proof of conformity for audits and incoming inspection. The presence of a calibration document increases confidence in repetitive checks and helps fulfil customer or regulatory requirements without delay.

Practical design and conformity for fine‑thread applications

The gauge follows DIN 13 with tolerance class 6g, matching the standard specification for metric fine threads and ensuring compatibility with common engineering practice. The right‑hand geometry is optimised for standard external thread forms, and the nominal designation M120 x 4.0 identifies the thread diameter and pitch clearly. With a mass of approximately 2.2 kg, the ring provides robust feel in handling and resists inadvertent distortion during normal shop use, supporting consistent measurements across production shifts.

FAQ

What does the GO designation mean for this thread gauge?
The GO designation indicates the ring is a pass gauge for external threads; the Thread ring gauge GO M120 x 4.0 must fit onto a part for that part to pass the acceptance check.

Is a calibration certificate supplied with the gauge?
Yes — this ring gauge is supplied with a calibration certificate, enabling documented traceability for quality records and inspections.

Which standard and tolerance does the gauge follow?
The gauge conforms to DIN 13 with tolerance class 6g, matching common specifications for metric ISO fine threads.

For which applications is this ring gauge appropriate?
The gauge is intended for production and incoming‑goods inspection of external metric fine threads such as M120 x 4.0, where quick go/no‑go verification is required.

What material is the gauge made from and how does that benefit use?
Constructed from hardened gauge steel, the ring offers high wear resistance and dimensional stability, ensuring long service life and repeatable checks.
