Thread ring gauge UNC GO, 5/8‑11, ANSI/ASME B1.1 – Metav IndustryLine

A thread ring gauge UNC GO, 5/8 x 11 ANSI B1.1 / 2A designed for fast go/no‑go verification of external UNC threads in production and quality control.

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 thread form
• Tolerance class 2A for consistent fit
• Compact 5/8‑11 UNC GO ring gauge

Reliable pass/fail inspection that saves time on the shop floor

A GO ring gauge provides instant acceptance testing for external threads: it confirms whether a thread falls within the permitted maximum material condition. Made from hardened gauge steel, the ring resists wear and preserves the reference profile over many cycles, which reduces rework and inspection variability. Conformance to ANSI/ASME B1.1 ensures compatibility with UNC thread specifications, while the 2A tolerance gives a predictable fit class for common assembly tasks. This delivers measurable gains in throughput and inspection reliability for routine checks.

Built for repeated use and simple handling in production environments

The compact 5/8‑11 size and robust construction suit bench inspection and inline control stations where space and speed matter. The gauge’s form factor makes it easy to seat on a spindle or hold by hand during checks, and hardened gauge steel minimises wear‑related uncertainty so calibration intervals can be extended. For workshops that prioritise dependable tooling, the combination of material choice and standardised thread form supports consistent results without complex setup.

Fits into documented quality routines and traceable measurement workflows

Using a standardised ring gauge simplifies documentation and acceptance criteria in quality records. The presence of the ANSI/ASME reference on the item helps auditors and inspectors quickly verify the applied standard. Lightweight and compact, the gauge is suitable for calibration programmes and inventory as a reference artefact; product traceability is supported by the listed GTIN and article identifiers in the technical data. Where procedural clarity and repeatability are required, the ring gauge integrates efficiently into existing inspection plans.
