No-go thread ring gauge M90 x 4.0 (right-hand) – Metav IndustryLine

A no-go ring gauge for metric ISO fine threads, designed for rapid assessment of M90 x 4.0 right-hand external threads in production and inspection environments.

• No-go ring gauge M90 x 4.0 right-hand
• Hardened gauge steel construction
• Supplied with calibration certificate
• Conforms to DIN 13 tolerance class 6g

Guaranteeing thread conformity with a single test

The no-go ring gauge is a rapid, unambiguous tool for thread inspection in series production. As a dedicated reject gauge, it verifies whether external threads exceed the upper tolerance limit: if the ring does not assemble onto the thread, the part conforms; if it fits, the thread is out of tolerance and must be rejected or reworked. This simple go/no-go principle streamlines quality control, reduces inspection time and eliminates subjective interpretation, making the gauge particularly suited to high-throughput metalworking and assembly operations.

Built for durability and standards-based accuracy

Manufactured from hardened gauge steel, this ring gauge resists wear and preserves dimensional integrity through many inspection cycles. It is produced to DIN 13 with tolerance class 6g, ensuring compatibility with standard metric ISO fine-thread specifications. The construction and finish make it robust against handling in workshop and shop-floor conditions while maintaining the precision required for reliable pass/fail decisions. Supplied with a calibration certificate, the gauge provides documented traceability for audits and quality records.

Practical integration into inspection routines

Using a dedicated reject gauge simplifies process control: inspection personnel obtain immediate, binary results and can segregate non-conforming parts without time-consuming measurements. The gauge’s size — M90 x 4.0 — and right-hand orientation match common fine-thread applications in heavy assemblies and mechanical components. For production planners and quality engineers, the gauge reduces cycle-time per inspection and supports consistent lot acceptance criteria, contributing to lower rework rates and improved throughput across machining and assembly stages.
