The JBO Thread Ring Gauge (GO) is a precision measurement tool designed to quickly verify external thread diameters on fasteners, fittings, and machined components. It is tailored for metric fine threads, specifically M56 x 2 right-hand threads, providing fast, reliable go/no-go checks to confirm parts meet exact specifications.

Built for daily use in workshops, QA labs, and manufacturing environments, this GO gauge features Class 6g tolerance and hardened steel construction for durability and long service life. Its simple, straightforward design lets inspectors and technicians identify conforming threads at a glance, supporting consistent quality control and precision engineering.

• Precise GO gauge for Metric Fine M56 x 2 Right-Hand threads: Delivers quick and reliable conformance checks of external threads, helping inspectors verify minimum diameter and fit while reducing rework and faster quality passes.
• Hardened steel construction for long life: Withstand daily shop wear, resist wear and corrosion, ensuring durable performance over thousands of tests in demanding environments.
• User-friendly, repeatable testing for QC workflows: Intuitive GO indication and compact form simplify threading checks, enabling consistent results across operators and shifts.

Using the JBO Thread Ring Gauge (GO) helps speed up thread inspection in production and QC settings, reduces rework and returns from misthreaded parts, and supports consistent, reliable results across production runs. Its hardened steel build stands up to daily use, while the clear GO indication and metric fine specification simplify decision-making for buyers, inspectors, and technicians alike, improving workflow and confidence in every threaded connection.
