Thread plug gauge UNF 5/16 x 24, 2B — Metav IndustryLine, hardened gauge steel, ANSI/ASME compliant

A Thread plug gauge UNF 5/16 x 24, 2B designed for verification of right‑hand internal threads to ANSI/ASME B1.1/B1.2 standards in workshop and production environments

• Right‑hand UNF 5/16 x 24, 2B tolerance
• Hardened gauge steel construction
• Manufactured to ANSI/ASME B1.1/B1.2
• Compact approx. 0.1 kg handling weight

Ensure thread conformity with a standards‑grade inspection tool

The plug gauge offers a direct method to confirm that internal threads meet specification: the 5/16 x 24 UNF form with 2B tolerance verifies fit and functional clearance according to ANSI/ASME B1.1/B1.2. Made from hardened gauge steel, the gauge resists wear in repeated use and gives a stable reference for pass/fail assessments on machined bores. Using a standards‑conforming gauge reduces the need for destructive testing and supports consistent assembly quality across batches, helping to prevent rework and reduce scrap.

Practical inspection that integrates into workshop routines

This right‑hand thread gauge is lightweight (approx. 0.1 kg) and compact, enabling quick manual checks at the machine or in the inspection bay. The 2B classification indicates the internal thread tolerance zone typically required for general engineering applications, providing clear acceptance criteria without complex measurement devices. For routine quality assurance, the gauge functions as an immediate tactile test of thread form and pitch (24 threads per inch), saving time compared with full metrological inspection while maintaining reliable control over thread production.

Built for traceability and dependable supply

Configured by Metav IndustryLine under industry classification eClass 21170214, the gauge is intended as a shop‑floor tool for production validation and incoming inspection. Compliance with ANSI/ASME B1.1/B1.2 ensures the reference is compatible with international machining and assembly practices. Relying on a tested, hardened gauge supports reproducible checks and helps document conformity in quality processes. Metav’s distribution and quality filter in Emmerich back supply reliability and product choice, making standards‑based inspection readily accessible even for smaller workshops.

FAQ

What does the 2B tolerance class mean for internal threads?
The 2B tolerance class defines the standard internal thread tolerance and fit for general engineering; the thread plug gauge verifies that an internal thread conforms to the 2B specification for proper assembly with mating external threads.

Is this gauge suitable for international production standards?
Yes, the plug gauge is manufactured to ANSI/ASME B1.1/B1.2, making it suitable for use in environments following these international thread standards.

What material is the gauge made from and why does it matter?
The gauge is made from hardened gauge steel, which provides wear resistance and dimensional stability during repeated inspection cycles, ensuring longer service life as a reference tool.

Can the gauge check left‑hand threads?
This item is produced as a right‑hand thread plug gauge; left‑hand versions require a separate designation.

How is thread pitch specified on this gauge?
Thread pitch is given as 24 threads per inch, which corresponds to the UNF specification for the 5/16" nominal size.
