The JBO Thread Ring Gauge (GO) is a precision tool designed to quickly verify external metric threads. Specifically configured for metric fine threads, it helps ensure parts with M3 x 0.3 are within tolerance, making it an essential addition to quality control, machining, and assembly workflows. Built for right-hand threads and 6g tolerance class, this gauge supports reliable pass/fail decisions across a range of small-fastener applications.

This GO gauge is crafted from hardened steel to withstand daily use in demanding workshop environments. Its durable construction delivers long service life and consistent performance, even after repeated insertions and inspections of threaded components.

• Precise Metric Fine Go Gauge (M3 x 0.3, Right-Hand, 6g): Quickly confirms external thread size and pitch against standards, enabling fast, confident acceptance or rejection of parts.
• Hardened Steel Construction: Provides superior wear resistance and durability for reliable measurements in busy inspection rooms.
• User-Friendly Quick-Check Design: Easy to interpret results at a glance, reducing inspection time and supporting consistent quality control outcomes.

By using this GO gauge, inspectors and machinists can streamline QC processes, minimize rework, and maintain tighter dimensional control across production runs. Its precise dimensions and robust build help you deliver repeatable, trustworthy results, contributing to smoother workflows and higher overall quality.
