Thread ring gauge UNF NOGO, 7/16 x 20 ANSI B1.1 / 2A (M315.983.F)

The thread ring gauge designed for quick go/no-go verification of UNF 7/16 x 20 internal threads in production and inspection environments.

• NOGO ring for UNF 7/16-20
• Conforms to ANSI/ASME B1.1/B1.2
• Hardened gauge steel construction

Faster pass/fail checks for threaded assemblies

The NOGO configuration is tailored for rapid quality control: it verifies that an internal thread is not larger than the maximum permitted envelope, enabling immediate rejection of out-of-tolerance parts. Manufactured from hardened gauge steel, the ring maintains dimensional stability under repetitive handling, so the inspection routine becomes both quicker and more reliable. The compact design supports straightforward insertion into typical bores, reducing cycle time at the inspection station.

Built to industry standards for dependable results

Compliance with ANSI/ASME B1.1/B1.2 gives a clear normative basis for thread geometry and ensures the gauge references accepted UNF definitions. The marked tolerance class 2A indicates the standard commercial fit associated with UNF external threads; the ring is produced to mate with that established envelope for consistent evaluation. The combination of standard conformity and a dedicated NOGO function makes this ring suitable for production lines, receiving inspection and in-process checks where clear binary decisions are required.

Practical advantages in workshop and metrology use

A hardened construction delivers wear resistance and long service life, which lowers lifetime inspection cost and minimises recalibration frequency. The ring’s right-hand thread orientation matches common fastener practice, eliminating confusion during routine checks. Traceable identification with SKU M315.983.F simplifies inventory control and tool management, while the compact weight and form factor make storage and handling straightforward in both workshop and laboratory settings.

How the gauge supports quality assurance workflows

Using a dedicated NOGO ring gauge streamlines go/no-go inspection to a single, objective action: either the ring enters the component (fail) or it does not (pass). This reduces subjective interpretation and speeds operator decisions, improving throughput without sacrificing assurance. Where documentation is required, the gauge’s conformity to recognised standards assists in audit trails and quality reports, enabling clear communication between production, quality and procurement functions.

FAQ

What does NOGO mean for this ring gauge?
The NOGO designation indicates that the ring is used to detect oversize internal threads; if the ring enters the component the thread is out of tolerance and must be rejected when using the thread ring gauge UNF NOGO, 7/16 x 20 ANSI B1.1 / 2A (M315.983.F)

Is this gauge suitable for production line inspection?
Yes, its hardened construction and conformity to ANSI/ASME B1.1/B1.2 make the gauge appropriate for repetitive production checks and routine go/no-go inspection with the thread ring gauge from Metav IndustryLine

Which materials was the gauge made from?
The gauge is manufactured from hardened gauge steel, chosen for wear resistance and dimensional stability under frequent use

How is the tolerance class 2A relevant to the inspection?
Tolerance class 2A corresponds to the standard external thread envelope; the ring is produced to mate with those dimensions, providing a recognised reference for go/no-go assessment with this NOGO ring

Can the gauge be traced in inventory systems?
Yes — the product is identified as M315.983.F and carries the GTIN 4054469180885 for straightforward inventory and procurement tracking
