The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric fine threads with confidence. It’s ideal for engineers, inspectors, machinists, and workshop teams working with left-hand threaded components. This NoGo gauge helps confirm that M34 x 1.5 threads meet the required size and engagement standards, ensuring reliable mating and consistent performance in assemblies.

Built to withstand daily use, this gauge is machined from hardened steel and finished to a strict 6g tolerance. The metric fine specification and left-hand orientation deliver durable, repeatable measurements, resisting wear and maintaining accuracy even in demanding shop environments.

• Exact M34 x 1.5 Left-Hand NoGo Spec: Delivers precise, repeatable pass/fail checks for external threads, reducing guesswork and speeding quality inspections.
• Hardened steel construction for durability: Resists wear, corrosion, and impact, ensuring long tool life and stable measurements in tough work conditions.
• User-friendly left-hand orientation and clear marking: Facilitates quick setup and easy identification of non-conforming parts, boosting workflow efficiency.

Used as a reliable part of quality control and threading inspection, the JBO Thread Ring Gauge helps you reduce downtime, minimize scrap, and maintain consistent thread quality across batches. Its robust build and precise NoGo specification support faster, more confident decisions during assembly and maintenance, making it a dependable addition to any metrology toolkit.
