The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6e, M48 x 1.5 – is a precision tool for verifying external thread diameters on metric fasteners and threaded components. It’s designed for engineers, machinists, quality inspectors, and assembly teams that rely on fast, repeatable go/no-go checks to confirm parts meet exact thread specifications.

Crafted from hardened steel and finished for durability, this gauge delivers long-lasting performance in busy shops and on production lines. Its rugged construction resists wear while maintaining accurate measurements, so you can trust results from the first part to the last, even in demanding environments.

• Precise metric NoGo for M48 x 1.5 right‑hand threads: Quickly verify that the external thread diameter stays within specification (6e), helping you separate compliant parts from out‑of‑tolerance ones with a single measurement.
• Hardened steel construction for durability: Withstand daily use in demanding environments, resist wear, and preserve measurement accuracy over time for reliable, repeatable results.
• User-friendly design for fast inspections: Knurled edge for secure handling, clear orientation cues, and a red marker to aid quick alignment, so operators can perform checks confidently and quickly.

Together, the JBO NoGo ring gauge streamlines inspection workflows, speeds up quality control, and reduces rework by providing clear, reliable pass/fail results for metric threads. Built to last, it maintains accuracy through heavy use, helping your team deliver precise assemblies and safer, more reliable products.
