Hardened gauge steel construction
Tolerance class 2A, ANSI/ASME B1.1
Designed for manufacturing quality control

Faster in-line acceptance with standardised GO checks

A dedicated GO ring gauge simplifies routine inspections by confirming that external UNC threads are within the permitted 2A envelope. By applying a single go/no-go decision criterion, the gauge reduces inspection time and avoids ambiguous manual measurements, supporting consistent throughput on the shop floor. The gauge’s specification to ANSI/ASME B1.1 means compatibility with widely used UNC thread systems, enabling straightforward integration into existing quality control procedures and sampling plans.

Durable design for reproducible results across production shifts

Manufactured from hardened gauge steel, the ring gauge offers wear resistance and dimensional stability that sustain repeatable results under frequent use. The compact nominal size 1 1/2" x 6 and clear tolerance class make the tool straightforward to store and handle during inspection cycles. Supplied as article M315.965, the component’s construction minimises scoring and false readings, which in turn reduces unnecessary rework and downtime within fabrication and inspection workflows.

Practical fit for shop-floor and QA environments

Intended for external thread verification, this go-only ring is optimised for pass/fail evaluations where a single confirmation is required before assembly or shipment. The 2A tolerance classification identifies the gauge specifically for external threads, clarifying its role in inspection plans and preventing misuse. When used as part of a controlled sampling routine, the gauge contributes to traceable quality records and supports decision-making that keeps production moving without compromises to conformance.

FAQ

What does the GO designation mean for this ring gauge?
The GO designation indicates the ring is used to confirm that external threads meet the minimum form and size requirements; the Thread ring gauge UNC GO, 1 1/2" x 6, ANSI/ASME B1.1, 2A permits parts that pass the gauge to proceed without further thread-size rejection checks.

Is this gauge suitable for production sampling on UNC threads?
Yes — the ring gauge is manufactured to ANSI/ASME B1.1 and is specifically designed for quick acceptance checks of UNC external threads in production environments.

What materials is the gauge made from and how does that affect service life?
The gauge is made from hardened gauge steel, providing high wear resistance and dimensional stability that prolongs service life under frequent shop-floor use.

Can this gauge be used for internal threads or for NO-GO evaluation?
This item is a GO ring intended for external thread acceptance; it does not serve as a NO-GO or internal thread gauge and should be used accordingly in inspection routines.

How should the gauge be stored and handled to maintain accuracy?
Store the ring in a clean, dry environment and avoid impacts or contamination. Regular visual checks and periodic dimensional verification maintain reliability for shop-floor inspections.
