Thread ring gauge UNC No. 10‑24 (NOGO) — hardened gauge steel, ANSI/ASME B1.1 compliant

The Thread ring gauge UNC No. 10‑24 (NOGO) is a hardened ring gauge designed for rapid verification of external UNC threads to ANSI/ASME B1.1 with tolerance class 2A

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 standards
• NOGO ring for fast rejection checks
• Size No. 10‑24, tolerance class 2A

Faster go/no-go inspection to reduce production downtime

The hardened NOGO ring is engineered for rapid pass/fail checks on external UNC threads, enabling immediate separation of out-of-tolerance parts from the production stream. By using a dedicated no-go gauge, dimensional checks are performed without the need for time‑consuming measurements, which improves throughput and lowers the risk of downstream assembly faults. The simple go/no‑go workflow translates directly into fewer rejects and shorter inspection cycles.

Standards-based accuracy for consistent quality control

Manufactured to match ANSI/ASME B1.1 dimensions and specified as tolerance class 2A, this ring gauge provides a reliable reference for thread form and size. The designation No. 10‑24 identifies the nominal thread size and 24 tpi pitch, so checks are directly comparable with drawing specifications and inspection plans. Traceable gauges such as this one simplify documentation and ensure that quality checks remain consistent across shifts and operators.

Durable construction for long service life in workshop conditions

Made from hardened gauge steel, the ring combines wear resistance with stable geometry so that repeatability is maintained over extended use. The compact, single-piece format is easy to handle and resilient against typical workshop handling. Routine care — cleaning debris, light oiling and storage in a dry place — preserves the gauge’s performance and extends service intervals. The robust design suits bench inspection and short quality-control loops without specialised fixtures.

FAQ

What does the NOGO designation mean for this ring gauge?
The NOGO feature indicates the ring is used to confirm that an external UNC thread exceeds permissible limits; the Thread ring gauge UNC No. 10‑24 (NOGO) must not enter a correctly formed external thread, thereby signalling oversize or malformed threads.

Which standard does this gauge comply with?
This ring gauge is specified to ANSI/ASME B1.1/B1.2, providing a direct reference to standard UNC thread form and dimensions for the No. 10‑24 size.

Can the gauge be used for serial production checks?
Yes — the hardened construction and single‑purpose no‑go design make M315.978 suitable for rapid, repeatable pass/fail inspections on production lines and assembly stations.

How should the ring gauge be cared for to maintain accuracy?
Regular cleaning of chips and lubrication of the annular surface will preserve geometry; store the gauge dry and protected to avoid corrosion and impact damage that could affect repeatability.

Is the ring suitable for all component materials?
The ring gauge verifies thread geometry irrespective of workpiece material; M315.978 checks external threads on parts made from typical workshop materials provided the threads conform to the No. 10‑24 UNC specification
