The JBO Thread Ring Gauge (NoGo) — Metric Fine — Right Hand — 6h — M45 x 1.5 is a precision inspection tool designed to verify external thread diameters with clarity and speed. Built for engineers, machinists, quality teams, and maintenance professionals, it helps you confirm whether a threaded part meets the NoGo limit on metric fine threads, reducing guesswork and rework in your workflow.

Crafted from hardened steel for exceptional durability, this ring gauge provides reliable performance in demanding environments. Its precise construction and exact dimensions support consistent inspections, helping you verify compliance with required standards and specifications across audits and production runs.

• Precise NoGo verification for metric fine threads: Quickly confirm whether an M45 x 1.5 external thread falls inside the acceptable NoGo limit, helping you detect out-of-tolerance parts before they reach assembly.
• Durable hardened steel construction: Built to withstand daily use in busy workshops, resisting wear and maintaining accuracy over time.
• Right-hand, 6h geometry for consistent results: Specifically matched to standard metric fine-thread specs, delivering repeatable measurements across parts and operators.

Using this gauge in your inspection routine speeds up quality checks, reduces downtime, and improves the reliability of threaded assemblies. It provides clear, pass/fail guidance for M45 x 1.5 threads while withstanding the rigors of busy production environments, giving you confidence in every measurement and every job.
