JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M52 x 1.5

The JBO Thread Ring Gauge GO - Metric Fine is a precision inspection tool designed to verify external thread diameters on threaded components. In right-hand M52 x 1.5 size with a 4h tolerance, this GO gauge helps teams in manufacturing, automotive, hydraulics, and maintenance quickly confirm that parts will thread on cleanly and consistently, reducing guesswork during assembly and quality checks.

• Fast go/no-go verification: delivers immediate pass/fail results so inspectors can confirm threads meet the maximum material condition without slower trial fits, speeding up quality checks and minimizing downtime.
• Durable hardened steel construction: built to withstand daily use in busy workshops, providing reliable performance and long service life even in abrasive or demanding environments.
• Standardized metric fine sizing: precisely matched to M52 x 1.5 right-hand threads with a 4h tolerance, ensuring consistent, repeatable checks that align with common engineering drawings and industry standards.

Used in quality control and assembly workflows, this GO ring gauge helps you verify that external threads conform to exact specifications on the first attempt. By enabling quick, accurate checks, it supports faster setup, reduces rework, and improves overall accuracy and interchangeability across threaded components.
