The JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 4h, M68 x 1.5 — is a precision external thread gauge designed to quickly verify diameter accuracy on threaded parts. It helps inspectors, engineers, and machinists confirm parts meet the NoGo limit and the M68 x 1.5 specification, delivering reliable, repeatable checks in quality-control workflows.

• NoGo gauge for Metric Fine threads: Verifies external thread diameters against the NoGo limit for M68 x 1.5 (4h) so you can make fast go/no-go decisions and ensure parts meet spec every time.
• Hardened steel construction for durability: Built to resist wear in busy workshops, maintaining accurate readings and offering long service life even in tough environments.
• Ergonomic grip with quick orientation: Knurled outer edge provides a secure grip, while a red alignment mark speeds setup and helps you read the gauge quickly and correctly.

This gauge helps streamline thread inspection, reduce rework, and improve consistency across batches by delivering precise, repeatable measurements of external threads. With its rugged materials and user-focused design, you can trust it to support reliable quality control and precise tooling alignment in daily operations.
