The JBO Thread Ring Gauge (GO) for Metric Coarse threads is a precision inspection tool that quickly verifies external thread diameters against a fixed Go limit. Designed for quality control professionals, machinists, and assembly technicians, it helps ensure M1.8 x 0.35 coarse threads meet target tolerances and proper engagement before final assembly.

• Precise Go gauge for metric coarse threads: Sized for M1.8 x 0.35, this gauge enables fast go/no-go checks to confirm the major diameter and thread form meet the specification.
• Hardened steel construction for durability: Built to withstand frequent use in busy workshops, resisting wear to preserve accuracy and extend service life.
• Right-hand, 6g tolerance class for standard threading: Aligns with industry standards for reliable mating with female threads and consistent results across parts.

Used in routine QC, the JBO Thread Ring Gauge (GO) helps you quickly confirm that M1.8 x 0.35 metric coarse threads will assemble correctly, reducing downtime and guesswork. By delivering repeatable go/no-go results, it supports consistent part fit, faster inspections, and higher-quality assemblies across production, repair, and maintenance tasks.
