Thread ring gauge UNEF GO 1 1/2" x 18, 2A — Metav IndustryLine

Thread ring gauge UNEF GO 1 1/2" x 18, 2A for verification of external UNEF threads in machining and inspection environments according to ANSI/ASME standards

• UNEF 1 1/2" x 18 GO gauge
• Hardened gauge steel construction
• ANSI/ASME B1.1/B1.2 compliance
• Tolerance class 2A for external threads

Reliable conformity assurance for production control

The GO ring gauge is designed to confirm that external threads meet maximum-material-size requirements defined by ANSI/ASME B1.1. Built to the 2A tolerance, this gauge provides a clear, pass/fail check that reduces subjective judgement during inspection and helps maintain throughput by lowering false rejects. By integrating a standardised check tool into the workflow, measurement uncertainty from manual comparison is minimised and repeatable measurements become part of routine quality control.

Durable construction for sustained workshop use

Manufactured from hardened gauge steel, the instrument offers wear resistance and dimensional stability over prolonged use, supporting consistent results across production batches. The designation as a GO gauge means it must freely enter a compliant external thread; failure to pass indicates oversize material or incorrect pitch. The item is finished for right-hand applications and its compact mass (0.7 kg) eases handling during frequent inspections while preserving the necessary profile stiffness for accurate verification.

Practical fit for inspection benches and toolrooms

Suited to machine shops, toolrooms and incoming inspection, the gauge simplifies thread acceptance procedures and feeds directly into documented quality processes. Traceability is supported by standard identifiers and durable marking, assisting in batch records and audits. Supplied by a quality-conscious partner, the device contributes to dependable traceable inspection routines and helps embed consistent thread verification into everyday production management.
