Thread ring gauge UNC NOGO, 7/16 x 14 ANSI/ASME B1.1 / 2A — NOGO ring gauge by Metav IndustryLine

The Thread ring gauge UNC NOGO, 7/16 x 14 is a hardened NOGO ring gauge designed for rapid go/no‑go inspection of external 7/16‑14 UNC threads to ANSI/ASME B1.1 standards, intended for production quality control and incoming goods inspection.

• ANSI/ASME B1.1 standard conformity
• Hardened gauge steel construction
• NOGO design for rapid reject detection
• Compact 7/16‑14 UNC size

Built for fast, reliable go/no‑go inspection

The hardened construction of this NOGO ring provides a durable inspection solution that tolerates frequent handling in a production environment. By checking only the NOGO condition, the gauge allows immediate identification of out‑of‑tolerance parts, which streamlines sorting and reduces downstream rework. The adoption of ANSI/ASME B1.1 geometry ensures the measured threads meet a widely recognised standard, simplifying supplier acceptance and audit documentation. The compact form factor supports quick, repetitive checks without the need for complex setup.

Precision where it matters for production control

Manufactured from hardened gauge steel, the ring retains its functional dimensions under continuous use, delivering consistent results over many inspection cycles. The tolerance class 2A designation reflects the intended mating class for external threads, enabling clear pass/fail decisions when paired with corresponding GO gauges or mating parts. For production lines where throughput and traceability are priorities, the NOGO ring reduces measurement time while maintaining the technical rigor required in metalworking and assembly operations.

Practical benefits for workshop and inspection stations

Using a dedicated NOGO ring reduces operator interpretation and speeds up quality checks at the line or at incoming inspection. The tool is optimised for external threads of size 7/16‑14 UNC, with 14 tpi pitch, so it integrates seamlessly into workflows for imperial‑sized fasteners and machined components. Its robustness minimises maintenance needs and supports a predictable inspection cadence—advantages that translate into lower process variability and improved overall equipment effectiveness (OEE).

FAQ

What does NOGO mean for this thread ring gauge?
NOGO indicates the ring is used to detect oversize or out‑of‑tolerance external threads; the Thread ring gauge UNC NOGO, 7/16 x 14 must not pass a part that exceeds allowable limits.

Is the gauge compatible with other standards?
This NOGO ring follows ANSI/ASME B1.1, so it is intended for components specified to that standard and is suitable for typical imperial UNC thread inspection.

What material and durability can be expected from the ring?
The ring is made from hardened gauge steel, offering wear resistance and dimensional stability for repetitive inspection tasks.

Can this gauge be used for functional assembly checks?
While primarily a go/no‑go inspection tool, the NOGO ring provides a quick functional check against the 7/16‑14 UNC mating envelope; it should be complemented with GO gauges or mating parts for full assembly validation.
