The JBO Thread Ring Gauge (GO) for UNEF is a precision go gauge designed to verify external thread diameters quickly and reliably. It serves machine shops, manufacturers, maintenance teams, and quality control professionals by confirming that UNEF-threaded components meet the required size and pitch.

Crafted from hardened steel for exceptional wear resistance, it withstands daily use in demanding environments. The user-friendly design enables easy alignment and fast, unambiguous go/no-go checks, helping inspectors determine conformity in seconds.

• Hardened steel construction: Built to withstand routine use in demanding environments, delivering wear resistance and long service life for accurate measurements over time.
• Precise UNEF GO size (Right Hand, 2A, 1 1/16 x 18): Engineered to match the GO thread diameter and pitch with consistent tolerance, enabling quick pass/fail checks and reliable gauging across batches.
• Easy go/no-go inspection: Provides intuitive feedback for fast, confident decisions and reduces downtime in inspections and assembly processes.

This gauge integrates into standard QC workflows, delivering consistent results across parts and shifts. By delivering a clear pass/fail indication, it helps streamline inspections, minimize rework, and support reliable assembly and maintenance performance.
