Thread ring gauge UNEF GO, 7/8 x 20 ANSI B1.1 / 2A — hardened gauge steel, right-hand thread

A Thread ring gauge UNEF GO, 7/8 x 20 ANSI B1.1 / 2A for rapid verification of external threads in machining and inspection environments

• UNEF 7/8 x 20, ANSI B1.1 standard
• Hardened gauge steel construction
• Tolerance class 2A GO gauge
• Right-hand thread

Fast pass/fail control for production lines

The Thread ring gauge UNEF GO, 7/8 x 20 ANSI B1.1 / 2A serves as a straightforward GO gauge for immediate assessment of externally threaded parts. Employed at the end of a turning or thread‑rolling operation, the gauge enables a quick pass/fail decision without time‑consuming measurements, speeding up throughput and reducing bottlenecks at inspection stations. The simple go/no‑go principle limits operator interpretation and supports repeatable acceptance checks.

Built for durability and standardised traceability

Constructed from hardened gauge steel, the ring maintains form and dimensional stability under frequent use, lowering the need for replacement and thus reducing total cost of ownership. Compliance with ANSI/ASME B1.1/B1.2 and specification as tolerance class 2A means the component meets widely recognised thread standards, simplifying documentation and audit trails. These attributes support reliable quality control across batches and shift changes.

Smooth integration into workshop inspection routines

Designed as a compact inspection tool, the gauge’s right-hand thread matches conventional external threads and permits swift engagement with the workpiece, improving handling ergonomics and cycle time. The robust construction delivers high repeatability across repeated checks, while the compact format makes the ring suitable for both inline inspection and bench checks. The clear GO function assists operators and QA personnel in maintaining consistent acceptance criteria.

FAQ

What is the primary purpose of this gauge?
The ring serves as a GO‑only inspection tool for external threads; the Thread ring gauge UNEF GO, 7/8 x 20 ANSI B1.1 / 2A confirms whether a threaded part meets the specified acceptance limit.

How does a GO ring gauge differ from a NOGO gauge?
A GO gauge checks that the part is within maximum material limits and assembles correctly; this particular GO ring gauge is intended solely for pass verification under the ANSI B1.1 criteria.

Is the material suitable for regular shop use?
Yes, the hardened gauge steel construction provides wear resistance and durability suitable for routine inspection in production environments.

Which standard does this gauge conform to and why does that matter?
The gauge conforms to ANSI/ASME B1.1/B1.2, which ensures compatibility with standard thread forms and simplifies documentation for quality systems.

What is the product SKU for ordering or traceability?
Refer to SKU M315.958.EF when ordering or recording the item for quality traceability.
