The JBO Thread Ring Gauge (GO) – Metric Fine, Left Hand, 6g, M16 x 1.5 is a precision go gauge designed to verify external metric threads. It’s ideal for machinists, inspectors, and quality teams working with left-hand threaded components who need quick, reliable checks to confirm the M16 x 1.5 specification is met.

• Accurate Go gauge for M16 x 1.5 left-hand threads: Provides fast, go/no-go verification of external thread diameters to the metric fine pitch standard, helping you confirm parts meet exact specifications without guesswork.
• Hardened steel construction for long service life: Built to withstand daily use in busy workshops, offering outstanding wear resistance and sustained accuracy over time.
• Left-hand, metric fine with 6g tolerance design: Specifically matched to left-hand thread components and the tight 6g tolerance, ensuring correct fit and reducing risk of mismatches in assemblies.

In everyday production and quality control, this gauge accelerates inspections, supports consistent thread quality, and helps prevent costly rework. Its durable construction and precise go/no-go design give your team confidence to move parts through the line quickly while maintaining strict standards.
