The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M135 x 3 is a precision inspection tool designed to verify external thread diameters on fasteners and machined parts. Ideal for engineers, machinists, quality teams, and workshop technicians, it provides fast, reliable go/no-go checks against the M135 x 3 right-hand thread specification.

• Precise GO gauge for Metric Fine threads: Enables quick go/no-go verification of external threads to the M135 x 3 right-hand specification, helping ensure parts meet exact standards.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, offering outstanding wear resistance and long service life.
• Right-hand, 6g tolerance for consistent results: Designed to match the 6g external thread class, supporting reliable conformance checks across parts and batches.

Using this gauge helps streamline inspections, reduce rework, and speed up assembly by providing clear pass/fail results for external threads. The durable construction and precise GO capability enable long-term reliability, lower downtime, and greater confidence when sourcing or manufacturing threaded components.
