Thread plug gauge UNC No. 1 x 64, ANSI B1.1 / 2B — Metav IndustryLine plug gauge for UNC internal threads

A Thread plug gauge UNC No. 1 x 64, ANSI B1.1 / 2B designed to verify internal UNC threads with standard 2B fit for production and inspection environments

• Hardened gauge steel construction
• ANSI/ASME B1.1/B1.2 compliant
• Tolerance class 2B for standard fit
• No. 1 size, 64 tpi thread form

Assured conformity for threaded assemblies

The plug gauge serves as a direct, tactile verification that internal threads meet the ANSI/ASME B1.1 profile and the specified 2B tolerance, providing a clear go/no-go decision at the workstation. As a physical inspection tool, it eliminates ambiguity in thread acceptance by translating geometric requirements into an immediate pass/fail result. This reduces downstream assembly problems and supports consistent interchangeability between mating parts.

Durable material for long service life

Manufactured from hardened gauge steel, this inspection gauge resists wear and preserves critical dimensions during repeated use. The robust material choice lowers the frequency of replacement and helps maintain measurement integrity across production batches. For workshops focused on uptime and predictable maintenance cycles, the gauge offers a durable inspection reference that contributes to fewer rejects and lower rework rates.

Clear specification simplifies quality control

Marked as No. 1 with 64 tpi, the gauge directly corresponds to the UNC series for fast identification on the inspection bench. Conformity to ANSI/ASME standards ensures compatibility with common engineering drawings and supplier specifications, streamlining incoming inspection and in-process audits. The simple binary assessment provided by a plug gauge complements dimensional measuring devices by offering a rapid functional check of thread form and basic fit.

Practical integration into inspection workflows

The compact, low-mass construction (approx. 0.1 kg) makes the gauge easy to handle during repetitive checks, while its single-purpose design keeps measurement routines efficient and traceable. Use alongside standard inspection documentation to record acceptance rates or as a quick verification during assembly. For teams that value clear process steps, the gauge provides a straightforward control point that supports quality management and reduces operator uncertainty.
