The JBO Thread Ring Gauge (GO) for Metric Fine threads verifies external thread diameters quickly and reliably, helping teams ensure parts meet exact standards. With the M17 x 0.5 right-hand thread specification, a 6g fit, and hardened steel construction, it delivers durable, long-lasting inspection performance in busy shops.

• Precise metric GO verification for M17 x 0.5: Delivers fast go/no-go checks to confirm compliant external threads, reducing guesswork and speeding up QA and acceptance workflows.
• Durable hardened steel construction: Built to withstand daily workshop wear, resisting wear and corrosion so measurements stay reliable over many inspection cycles.
• Right-hand, metric fine threading compatibility: Designed for right-hand, fine-pitch threads, enabling clear conformity checks and easy integration into standard measurement routines.

Together, these qualities translate into faster inspections, fewer bottlenecks, and more consistent thread quality across batches. The JBO Thread Ring Gauge supports reliable pass/fail decisions, reduces rework, and fits easily into standard QA processes, giving you confidence from receipt to final assembly.
