The JBO Thread Ring Gauge (GO) - Metric Fine is a precision go gauge designed to verify external thread diameters on fasteners, fittings, and machined parts. It helps identify threads that conform to exact size requirements, enabling reliable quality checks across engineering, manufacturing, and maintenance environments.

Designed for metric fine threads with a right-hand orientation, this gauge features 6h tolerance and size M13 x 1.5 to support consistent, repeatable inspection results.

• Go gauge for rapid conformance checks: Quickly verify external thread size against the M13 x 1.5 (6h) metric fine standard, speeding up inspections without guesswork.
• Hardened steel construction for durability: Built to withstand daily use, wear, and contact with components, delivering long service life in busy workshop or production environments.
• Clear, user‑friendly design for fast identification: Intuitive geometry and finish allow operators to confirm proper thread form at a glance, reducing inspection time and rework.

Using the JBO Thread Ring Gauge (GO) in Metric Fine provides a dependable, repeatable way to confirm external thread size at a glance. It supports streamlined quality control, helps minimize downtime from non-conforming parts, and promotes consistent results across lots. The robust hardened steel construction withstands frequent handling in demanding environments, helping you maintain accuracy from first part to last.
