Thread plug gauge UNC No. 3 x 48 ANSI B1.1 / 2B — Metav IndustryLine hardened gauge steel, ANSI‑compliant

The Thread plug gauge UNC No. 3 x 48 ANSI B1.1 / 2B is a dedicated inspection gauge for verifying internal UNC No. 3 threads to tolerance class 2B, suitable for production and incoming‑goods checks where ANSI/ASME compliance is required.

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 thread standard
• 48 tpi UNC No. 3 with 2B tolerance
• Traceable GTIN and SKU M315.913

Consistent, standardised thread inspection that reduces rework

Designed for production environments, this plug gauge checks internal UNC threads with repeatable accuracy. Manufactured from hardened gauge steel, the tool resists wear and maintains profile integrity over many cycles; compliance with ANSI/ASME B1.1 ensures results are accepted across suppliers and customers. The specified tolerance class 2B denotes the common internal thread fit for general engineering assemblies, and the 48 tpi pitch corresponds to the UNC No. 3 form, enabling clear go/no‑go assessment within established acceptance criteria.

Robust design for streamlined quality control

The gauge’s compact, low‑mass construction (approx. 0.1 kg) makes it simple to handle at the inspection bench while providing the stiffness required for reliable engagement with threaded bores. A hardened surface finish extends service life and lowers long‑term costs by reducing replacement frequency. Traceable identifiers such as SKU M315.913 and the GTIN facilitate inventory control and audit trails, supporting efficient batch acceptance and production flow without unnecessary stoppages.

Traceability and manufacturer confidence for audit‑ready processes

Identification via GTIN 4054469179360 and the clear designation of standard and tolerance simplify documentation for quality systems and parts lists. Integration into inspection routines is straightforward: the plug gauge serves as a primary reference for internal thread conformity and forms part of a documented measurement plan. Supplied under the Metav IndustryLine umbrella, the gauge benefits from Metav’s role as a quality filter in Emmerich, providing consistent sourcing and dependable availability for workshops and industrial users.
