The JBO Thread Ring Gauge (GO) - BSW is a precision tool designed to verify external thread diameters on components with British Standard Whitworth (BSW) threads. For right-hand threads and Medium class sizes, the 1 1/2 x 6 gauge provides fast, reliable go checks during inspection, assembly, and maintenance.

This gauge is crafted from hardened steel to deliver long-lasting durability in demanding work environments. Its straightforward design makes it easy to identify when a threaded part meets the specification, supporting consistent quality control across batches.

• Precise Go Gauge for BSW Right-Hand Threads: Quickly confirms external thread diameters meet spec, reducing inspection time and rework.
• Hardened Steel Construction: Delivers excellent wear resistance and long tool life in busy workshops and production lines.
• Go Gauge with Clear Pass/Fail Indication: Provides intuitive, quick identification of conforming parts to streamline quality control and precision engineering workflows.

Using this gauge helps you make fast, confident decisions during assembly and QC, reduces variability across parts, and supports reliable, repeatable results for threaded components. Its durability and simple operation keep inspections efficient, helping teams meet standards and maintain high overall performance across shifts.
