Thread plug gauge UNC, 2 in × 4.5 tpi — Metav IndustryLine; hardened gauge steel, ANSI/ASME B1.1, 2B

The Thread plug gauge UNC, 2 in × 4.5 tpi is a precision inspection gauge designed to verify internal UNC threads to ANSI/ASME B1.1/B1.2 standards with a 2B tolerance classification.

• Hardened gauge steel construction
• ANSI/ASME B1.1 compliant
• Tolerance class 2B
• 2 in × 4.5 tpi nominal size

Consistent acceptance criteria for production control

The plug gauge provides a clear, objective method for thread inspection, enabling efficient decisions at the inspection stage. Manufactured from hardened gauge steel, the tool maintains its profile under frequent use, which reduces rework and uncertain measurements. Conformity with ANSI/ASME B1.1 ensures that results are comparable across suppliers and customers, helping to uphold contractual specifications and minimise non‑conformances on the shop floor.

Robust construction for repeatable measurements

A stable gauge body and heat-treated material mean the instrument resists wear and deformation during routine checking. The 2B tolerance classification denotes standard internal thread acceptance for general engineering applications; using a purpose‑built plug removes operator guesswork and shortens inspection time. The mass and dimensioning aid comfortable handling and consistent seating in threaded bores, supporting a repeatable inspection cycle without elaborate fixturing.

Simple to integrate into quality workflows

This plug gauge is suitable for inline sampling or bench inspection and fits established quality procedures that reference ANSI/ASME B1.1. Labels and traceable article identifiers simplify inventory management and audit trails. Where traceability is required, the gauge can be logged with its SKU and GTIN for asset control, and routine inspection intervals can be scheduled according to internal quality plans to preserve measurement integrity.

Suits standards-driven workshops and suppliers

For procurement and inspection teams who prioritise standard compliance and longevity, the gauge offers a pragmatic balance between precision and durability. The UNC designation and 4.5 tpi pitch are commonly specified in mechanical and assembly work, so keeping a calibrated, hardened plug gauge on hand supports faster part acceptance and reduces delays at assembly or receiving. The product is an economical tool for ensuring thread quality across production batches.

FAQ

What standard does the gauge comply with?
The plug gauge conforms to ANSI/ASME B1.1/B1.2, and the Metav IndustryLine thread plug gauge (M315.937) is manufactured to meet those specifications.

Which nominal size and pitch are covered by this gauge?
This inspection tool is specified for a 2 in nominal size with a 4.5 tpi pitch, suitable for UNC internal thread checks.

What does tolerance class 2B mean for inspection?
Tolerance class 2B indicates the standard internal thread class for general engineering use; the Metav IndustryLine gauge provides a practical acceptance check against that class.

Is the gauge suitable for frequent shop‑floor use?
Yes. The hardened gauge steel construction of the Metav IndustryLine thread plug gauge is designed for repetitive inspection and retains its form under normal shop conditions.

How is the product identified for inventory and traceability?
The item is listed under article number M315.937 and GTIN 4054469179940, which supports straightforward asset tracking in quality systems.
