The JBO Thread Ring Gauge (NoGo) for Metric Fine threads is a precision tool designed to verify external thread diameters to the M78 x 1.5, right-hand, 6h specification. It’s ideal for inspectors, machinists, fabricators, and quality teams who need quick, reliable checks to ensure threaded components will assemble correctly.

• Precise NoGo verification for metric fine threads: Quickly confirms that external threads meet the M78 x 1.5, right-hand, 6h specification, helping you reject non-conforming parts at a glance and reduce rework.
• Hardened steel construction for long service life: Precision-ground and hardened to resist wear, maintaining accurate checks even in busy workshops and through heavy daily use.
• Easy, intuitive use with clear pass/fail readings: Simple alignment with the thread and a straightforward go/no-go result, enabling consistent inspections across operators.

Using the JBO Thread Ring Gauge streamlines quality checks, reduces downtime, and improves reliability across threaded components. It supports faster, more consistent inspections on M78 x 1.5 right-hand threads, with a durable build that withstands daily handling in manufacturing, assembly, or repair environments. By enabling precise, repeatable checks, this gauge helps minimize scrap, accelerate production, and ensure threads meet specification before assembly or delivery.
