Thread ring gauge NOGO — 5/8 x 24 UNEF, hardened gauge steel (Metav IndustryLine)

A thread ring gauge NOGO 5/8 x 24 UNEF designed for decisive verification of external UNEF threads according to ANSI/ASME standards

• No‑go ring gauge for UNEF 5/8‑24 threads
• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1/B1.2
• Tolerance class 2A, right‑hand thread

Consistent rejection criteria for reliable assemblies

The thread ring gauge NOGO 5/8 x 24 UNEF provides a clear, mechanical pass/fail decision that prevents oversized external threads from entering assembly. As a no‑go gauge, it is intended to detect parts that exceed the upper material limit: if the gauge fits, the part must be rejected. Compliance with ANSI/ASME B1.1/B1.2 and tolerance class 2A ensures compatibility with common fastener specifications and supports repeatable quality criteria across suppliers and production lines. This standardised approach limits downstream failures and contributes to predictable assembly yields.

Durable build to reduce downtime and maintain accuracy

Manufactured from hardened gauge steel, the ring resists wear and preserves the critical thread profile under frequent use. The robust material reduces dimensional change over time, which in turn lowers the frequency of replacement and recalibration. At approximately 0.4 kg the gauge combines handling convenience with sufficient rigidity for routine inspection tasks on the shop floor. The right‑hand thread orientation matches the predominant thread direction in production, simplifying inspection workflows without extra adaptation.

Fast inspection, simple integration into quality systems

Designed for quick, tactile checks, the ring enables immediate pass/fail sorting without complex measurement setups. The tool speeds up sampling and in‑line checks, freeing metrology benches for tasks that require detailed measurement. Integration into inspection routines is straightforward: pair the no‑go ring with corresponding go gauges for a complete go/no‑go system, record checks against SKU M315.986.EF for traceability, and include the gauge in routine quality audits to maintain documented process control. The result is faster decision‑making and fewer nonconforming parts reaching assembly.

FAQ

What is the purpose of a no‑go ring gauge?
A no‑go ring gauge stops parts that exceed the maximum material condition; the Metav IndustryLine no‑go ring gauge for 5/8‑24 UNEF is used to detect oversized external threads that must be rejected.

How does the Metav IndustryLine NOGO gauge relate to the go gauge?
The no‑go gauge complements a go gauge: the go must fit and the no‑go must not; together they define the acceptable thread envelope for production checks of UNEF threads.

Is this ring gauge suitable for shop‑floor inspection or only for the metrology lab?
The hardened gauge steel construction and compact mass make the gauge appropriate for both shop‑floor sampling and bench inspection, providing rapid pass/fail decisions without elaborate setup.

Which standard does the gauge follow and why is that important?
The gauge conforms to ANSI/ASME B1.1/B1.2; adherence to these standards ensures interchangeability with industry‑standard fasteners and consistent acceptance criteria across suppliers.

How should the gauge be referenced in documentation and stock systems?
Use the SKU M315.986.EF and GTIN 4054469180960 when recording inspections and inventory to ensure traceability and proper replacement planning.
