Thread ring gauge UNC NOGO 1 3/4" x 5 TPI, 2A (ANSI/ASME B1.1) — Metav IndustryLine

The thread ring gauge UNC NOGO 1 3/4" x 5 TPI, 2A is a precision go/no-go inspection gauge designed for verifying externally cut UNC threads according to ANSI/ASME B1.1 in production and quality‑control environments.

• Hardened gauge steel for extended service life
• ANSI/ASME B1.1/B1.2 compliance for standard conformity
• Tolerance class 2A for commercial thread fit
• NOGO function for reliable pass/fail control

Ensure fast, reliable pass/fail inspection on the shop floor

A dedicated NOGO ring gauge simplifies routine thread checks by delivering an immediate accept/reject decision: if the ring does not pass the external thread, the part exceeds maximum material condition and is rejected. This method reduces inspection time compared with full dimensional analysis and supports inline quality control. The compact check procedure helps maintain a steady production rhythm while lowering the rate of faulty assemblies and rework.

Designed for repeatable accuracy and long service life

Manufactured from hardened gauge steel, the gauge resists wear and maintains its profile over prolonged use, which preserves measurement reliability and reduces replacement intervals. The 2A tolerance class corresponds to a standard commercial external thread fit, making the tool suitable for many engineering and fabrication applications. The nominal size 1 3/4" x 5 TPI and compliance with ANSI/ASME B1.1 ensure the gauge matches established thread forms and pitches; this clarity eases communication between production, inspection and suppliers.

Clear conformity and traceability for quality assurance

Using a standardised NOGO gauge supports certification and audit requirements by demonstrating routine control steps in the manufacturing process. The simple go/no-go verdict complements more detailed inspection methods and serves as a documented checkpoint within a quality management system. Paired with Metav IndustryLine procurement, the gauge forms part of a predictable supply chain backed by traceable product data and consistent quality checks.

FAQ

What thread size and pitch does this gauge check?
The gauge checks UNC external threads at 1 3/4" diameter with 5 TPI, matching the specification printed on the Metav IndustryLine product.

Which standard does the ring gauge conform to?
This NOGO ring gauge is made to ANSI/ASME B1.1/B1.2 thread standards and is supplied for routine pass/fail inspection in line with those norms.

What does the 2A tolerance class indicate?
Tolerance class 2A denotes a standard commercial external thread fit; the gauge ensures that manufactured threads meet the expected mating and clearance behaviour for this class.

Is the gauge suitable for continuous use in production?
Yes. Constructed from hardened gauge steel, the ring is designed for repeated use with good wear resistance, making it suitable for shop‑floor and inspection‑bench applications.

How is a NOGO ring used in quality control?
A NOGO ring rejects parts that exceed maximum material condition; if the ring does not fit over the external thread, the component is considered out of tolerance and flagged for rework or scrap.
