The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric coarse threads, helping quality teams and machinists ensure parts meet exact standards. Sized for M36 x 4, with a 6e coarse-thread specification and right-hand orientation, this gauge provides a reliable go/no-go check that speeds up inspection and reduces guesswork in assembly and manufacturing workflows.

• NoGo Quick-Check for External Threads: Instantly identifies non-conforming parts by showing whether the M36 x 4, 6e coarse-threaded component fails to meet the NoGo limit, enabling fast, confident pass/fail decisions without trial-and-error threading.
• Durable hardened steel construction: Built to withstand daily use in busy shops and QC labs, resisting wear and maintaining dimensional accuracy for long-lasting, repeatable measurements.
• Designed for Metric Coarse, Right-Hand Threads: Optimized for the common coarse-thread standard (M36 x 4) with a right-hand thread, ensuring consistent results across typical parts and seamless integration into existing inspection routines.

This gauge supports proactive quality control by providing clear, dependable measurements that help ensure proper fitment and performance in threaded connections. Its robust build and straightforward operation reduce inspection time, improve consistency across batches, and give teams the confidence to approve components that meet exacting standards.
