Gewinde-Lehrdorn No. 2 × 64 UNF – Thread plug gauge, ANSI/ASME B1.1, 2B

The Gewinde-Lehrdorn No. 2 × 64 UNF is a right‑hand thread plug gauge intended for dimensional inspection of internal UNF threads in production and quality control environments.

• No. 2 × 64 UNF right-hand thread
• Tolerance class 2B to ANSI/ASME B1.1
• Hardened gauge steel construction

Ensure correct assembly fit with standardised inspection

The gauge is manufactured to ANSI/ASME B1.1 standards and calibrated to tolerance class 2B, providing a verifiable benchmark for internal thread acceptance. This standard conformity reduces ambiguity during quality checks and shortens decision time at the inspection bench: measurements are immediately comparable to accepted specifications and sampling protocols. The combination of a standard thread form and a clearly defined tolerance class supports fast acceptance or rejection of batches, thereby improving throughput and process reliability.

Robust construction for repeated shop‑floor use

Made from hardened gauge steel, the device resists wear from repeated contact and maintains dimensional stability under typical workshop conditions. The material choice ensures longevity of the inspection tool and consistent results over many cycles, which minimises rework and inspection downtime. The right‑hand No. 2 × 64 UNF configuration and compact design make the gauge suitable for confined inspection jigs and assembly fixtures where ease of handling and repeatability matter.

Practical benefits for quality assurance workflows

Using a dedicated thread plug gauge streamlines in‑process control: the presence of a physical master reduces reliance on subjective visual checks and supports traceable quality documentation. The gauge’s concise specification supports simple integration into inspection plans, control charts and final acceptance protocols. By standardising checks with a hardened reference, calibration intervals can be planned and documented efficiently, contributing to consistent production quality.

Metrology compatibility and traceability

This inspection tool sits squarely in industrial metrology practice: it complements optical comparators and digital measurement benches by providing a rapid go/no‑go assessment that is easy to interpret. The concise designation and compliance make it straightforward to record results and to align with internal standards or customer specifications. For organisations seeking to maintain a clear audit trail, the gauge’s normative reference helps anchor measurement procedures in internationally recognised rules.
