Thread ring gauge UNEF NOGO No. 12 x 32 — hardened gauge steel, ANSI/ASME B1.1 (Metav IndustryLine)

The Thread ring gauge UNEF NOGO No. 12 x 32 is a purpose-built NOGO ring for fast verification of external UNEF No. 12×32 threads according to ANSI/ASME standards, designed for inline inspection and workshop use

• NOGO only for external UNEF No.12 × 32 threads
• Hardened gauge steel for long service life
• Manufactured to ANSI/ASME B1.1 tolerances
• Tolerance class 2A ensures strict thread limits

Fast, reliable rejection control for production

This NOGO ring presents a compact and unambiguous control point for external threads. Built as a single‑function gauge, the device immediately identifies threads that exceed the upper material limit, enabling rapid segregation of non‑conforming parts and reducing downstream rework. The compact geometry and light mass make handling simple during repeated checks while the clear NOGO criterion shortens inspection cycles and supports a measurable increase in line throughput. Bold inspection routines become feasible without complex measurement set‑ups, improving overall equipment effectiveness.

Durable materials and standards for reproducible results

Constructed from hardened gauge steel, the ring resists wear and preserves the critical thread form over extended use, which maintains inspection integrity and lowers lifecycle cost. Manufactured to ANSI/ASME B1.1/B1.2 with tolerance class 2A, the gauge aligns with common North American thread specifications for external UN threads; this standardised conformity ensures interchangeability and straightforward integration into existing quality plans. Traceable identifiers such as GTIN and a clear SKU provide logistical transparency and ease of inventory control.

Practical fit into quality assurance processes

As a single‑purpose NOGO ring, the tool is particularly effective as a final check in assembly or as a spot‑check device on the shop floor. Its use supports documented acceptance/rejection criteria and can be included in control plans or work instructions with clear pass/fail logic. The modest weight and small footprint allow flexible placement at assembly stations or inspection benches, while the hardened construction reduces the need for frequent replacement. When combined with Metav IndustryLine procurement and stock availability, this gauge becomes a dependable element in stabilising production quality.

FAQ

What does NOGO mean for this ring gauge?
NOGO indicates the ring is a reject gauge: if the external thread enters the ring, the threaded part fails the check. The Thread ring gauge UNEF NOGO No. 12 x 32 by Metav IndustryLine is used solely to detect oversize or out‑of‑tolerance external threads.

Which standard is the gauge manufactured to?
The gauge is produced to ANSI/ASME B1.1/B1.2 specifications and complies with 2A tolerance class requirements for the stated UNEF No. 12 × 32 thread form.

Can this gauge be used for left‑hand threads?
No, the ring is specified as a right‑hand thread gauge. For left‑hand threads, a purpose‑made left‑hand ring must be used.

How does hardened gauge steel benefit routine inspection?
Hardened gauge steel provides wear resistance and dimensional stability, extending service life and maintaining the functional limit that the NOGO ring enforces during repeated checks.

Is the gauge suitable for inline assembly checks?
Yes, the compact form and unambiguous pass/fail function of this NOGO ring make it well suited to inline checks and spot inspections on the shop floor; it integrates easily into control plans.
