The JBO Thread Ring Gauge (GO) for Metric Coarse threads is a precision tool designed to quickly verify external thread sizes on fasteners, fittings, and mechanical components. Sized for M36 x 4 with a right-hand thread, this GO gauge helps quality teams and workshop staff confirm that parts meet exact coarse-thread specifications without guesswork.

Constructed from hardened steel for durability, the gauge stands up to daily use in busy production environments. Its precise dimensions ensure reliable checks for metric coarse connections across a range of components, making it a dependable part of any inspection routine.

• Accurate GO sizing for metric coarse threads: Quickly verify external thread diameter and pitch against the M36 x 4 (6e) specification, speeding inspections and reducing rework.
• Hardened steel construction for durability: Built to endure daily handling and wear, delivering long service life and consistent readings in demanding shop environments.
• User-friendly design for repeatable checks: Smooth engagement with threads and straightforward pass/fail results help technicians access reliable measurements with confidence.

This gauge supports precise, repeatable inspections, helping you ensure proper fitment and performance of metric coarse threaded connections. By delivering quick, confident checks, it reduces downtime, standardizes quality across parts, and supports efficient workflows in engineering, manufacturing, and maintenance environments.
