The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision measuring tool designed to verify internal metric fine threads. Specifically, it's used to check threaded holes and confirm they meet the upper-limit tolerance for M76 x 3, Right Hand, 6H specifications. This NoGo gauge helps quality teams quickly determine if holes are within spec, reducing rework and speeding up inspections.

Constructed from hardened steel for durability, this plug gauge resists wear in demanding environments and provides long-lasting measurement stability across many cycles. Its right-hand orientation and adherence to 6H tolerance ensure consistent, repeatable results that align with common manufacturing standards.

• Metric Fine NoGo design: Specifically built for metric fine threads, this gauge reliably checks the upper limit of M76 x 3 holes to prevent oversize features and ensure proper thread engagement.
• Hardened steel construction: Delivers enhanced wear resistance and long service life, maintaining accuracy even after numerous inspections in busy workshops.
• Right-hand orientation with 6H compatibility: Matches standard internal thread direction and tolerance class, enabling fast, confident checks that fit seamlessly into QC workflows.

Using this gauge, you can speed up quality checks, reduce rework, and improve consistency across manufactured parts. The durable construction and standard-compliant design help you trust your measurements, streamline inspections, and maintain reliable assemblies with confidence.
