Thread Ring Gauge UNC NOGO, 5/8 x 11 (ANSI/ASME B1.1) — Metav IndustryLine

The Thread Ring Gauge UNC NOGO, 5/8 x 11 ANSI B1.1 / 2A is a NOGO inspection gauge for rapid verification of UNC internal threads in workshop and quality‑control environments.

• NOGO ring to ANSI/ASME B1.1 specification
• Hardened gauge steel construction for durability
• Tolerance class 2A for reliable acceptance checks

Rapid, standards‑based pass/fail inspection

The NOGO ring is intended for quick verification: it indicates whether an internal UNC thread exceeds permitted material removal or tapering without measuring every detail. Built to ANSI/ASME B1.1, the gauge addresses the common UNC thread form 5/8 in × 11 TPI, providing decisive accept/reject feedback in a single operation. For production lines and inspection benches this reduces cycle time and simplifies workflow documentation, while maintaining traceability through the supplied identifiers.

Durable construction to lower life‑cycle costs

Manufactured from hardened gauge steel, the inspection ring resists wear and retains its functional dimensions under routine handling. Robust material and heat treatment minimise the need for frequent replacement, which lowers total cost of ownership and keeps inspection throughput steady. The compact design and balanced mass facilitate ergonomic handling during repetitive checks, supporting consistent application force and improving repeatability across shifts.

Seamless integration into quality routines

The gauge is supplied to match the 2A tolerance class, aligning it with common acceptance criteria in mechanical production and maintenance contexts. Markings such as SKU and GTIN support inventory control and traceability in inspection records. Suitable for workshop inspection tables and incoming‑goods checks, the instrument streamlines conformity assessment without requiring measurement expertise, allowing technicians to focus on corrective actions when a NOGO condition occurs.

FAQ

What does "NOGO" mean for this ring gauge?
A NOGO ring gauge prevents a part from passing if the internal thread is too far out of tolerance; the supplied NOGO ring gauge (5/8 × 11, 2A) therefore confirms rejection criteria according to the specified thread standard.

Can this gauge be used on plated or coated threads?
The hardened gauge steel construction is suitable for inspection of typical plated threads, but plating thickness should be considered when close to tolerance limits as the coating can affect fit.

Which standard does the instrument comply with?
The inspection ring is manufactured to the ANSI/ASME B1.1 thread form and is labelled for use with UNC 5/8 in × 11 TPI threads, matching common production and inspection specifications.

How should the ring gauge be handled and stored?
Handle the gauge with care to avoid knocks and contamination; store it dry and clean to preserve the hardened surface and dimensional integrity. Regular visual checks are recommended before use.

Is the gauge suitable for production line checks?
Yes — the design supports fast, unambiguous pass/fail decisions and is appropriate for recurring inspection tasks in production and incoming‑goods workflows.
