Thread plug gauge UNC, 9/16‑12 – 2B tolerance, hardened gauge steel (Metav IndustryLine)

The thread plug gauge UNC, 9/16‑12 is a compact Go/No‑Go gauge designed for the verification of internal UNC 9/16‑12 threads in production and quality control to ANSI/ASME B1.1 standards

• ANSI/ASME B1.1 conformity
• Hardened gauge steel construction
• Tolerance class 2B Go/No‑Go verification

Fast, repeatable Go/No‑Go inspection for threaded components

A plug gauge provides an immediate pass/fail decision: the Go‑end confirms correct internal form and pitch, the No‑Go‑end detects oversize defects. The hardened gauge steel body maintains dimensional stability across repeated use, reducing measurement drift and downtime. By using a tool matched to ANSI/ASME B1.1, shops minimise rework and ensure components meet accepted UNC thread geometry without complex set‑ups or optical inspection.

Robust material and careful handling to extend service life

Manufactured from hardened gauge steel, this plug gauge resists wear that would otherwise alter thread form. Regular visual inspection and light lubrication for storage prevent corrosion and preserve the measuring faces. For routine inspection cycles, the gauge's compact mass allows quick handling and stable seating in the workpiece, speeding throughput while keeping measurement uncertainty low. The combination of material choice and simple handling practice delivers consistent results over long production runs.

Standards, traceability and efficient quality documentation

Conformity to ANSI/ASME B1.1/B1.2 and a defined 2B tolerance class provide a clear criterion for acceptance in procurement and production documents. Traceability is supported by the included identifiers and GTIN, enabling straightforward record keeping within quality systems. Using a standardised plug gauge reduces subjective decision‑making on the shop floor, which streamlines audits and accelerates corrective actions when deviations occur.

Practical workflow: quick checks that protect downstream processes

Integrating the plug gauge into first‑article inspection or in‑line spot checks prevents the costly cascade of fitting and assembly errors. The gauge is suited to rapid verification during incoming inspection or final control, where a clear Go/No‑Go outcome reduces sorting time and supports just‑in‑time production. Where required, the straightforward test routine can be combined with documented sampling plans to balance speed and statistical confidence.

FAQ

What does the 2B tolerance class mean for internal threads?
The 2B tolerance class denotes the standard internal thread tolerance for general engineering applications; the thread plug gauge UNC 9/16‑12 checks that internal threads conform to that specific fit.

Can this plug gauge be used for incoming inspection of purchased parts?
Yes, the Metav IndustryLine thread plug gauge UNC 9/16‑12 is intended for incoming and in‑process checks, providing immediate Go/No‑Go results for UNC 9/16‑12 threads.

How should the plug gauge be stored to preserve accuracy?
Store the plug gauge in a dry, stable environment, lightly oiled if required; the hardened gauge steel construction resists wear, but correct storage prevents corrosion and protects the measuring faces.

Is the gauge suitable for serial production checks?
The gauge is engineered for repeated use in production settings; hardened material and ANSI/ASME compliance make it suitable for serial quality control and spot checks.

What identifiers are available for documentation and traceability?
The product is supplied with SKU M315.925 and GTIN 4054469179643 to support traceability, inventory control and quality documentation.
