The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6e - M38 x 1 is a precision tool designed for quick, reliable verification of external metric threads. Whether you’re a manufacturing engineer, quality inspector, machinist, or maintenance technician, this GO gauge helps you confirm that threads measure to the correct Go limit without guesswork. The ring’s knurled outer edge provides a secure grip for fast, one-handed handling during inspections.

Crafted from hardened steel, it’s built to withstand the wear of busy workshops and production lines. Its precise internal threading and overall dimensions stay consistent, so you can rely on repeatable checks across many parts and jobs. This durable construction supports long service life in demanding environments.

• Accurate GO verification for M38 x 1 threads: Quickly confirm the external thread reaches the Go limit, speeding up inspections while maintaining precision.
• Hardened steel construction for durability: Resists wear and maintains accuracy for long service life in demanding workshops.
• Metric fine, right-hand design (6e, M38 x 1): Ensures reliable, repeatable checks with standard metric threads used in a wide range of components.

With the JBO GO gauge, you reduce inspection time, improve part conformity, and minimize downtime from mis-sized threads. The consistent performance supports streamlined quality control and reliable results across machining, assembly, and maintenance tasks.
