The JBO Plug Gauge - UNF (STI) Heli Coil Gauge - Right Hand - 2B - No. 6 x 40 - Calibrated (DAkkS Calibration) is a precision tool built to verify the pitch diameter of Helicoil/ STI thread inserts. Aimed at engineers, machinists, inspectors, buyers, and technicians across manufacturing, automotive, and aerospace, it provides a reliable way to confirm insert dimensions and ensure proper fit in assemblies. With its right-hand orientation and 2B size specification, this gauge supports accurate, repeatable checks in fast-paced production environments.

These gauges are manufactured and assessed in accordance with ANSI standards, specifically the ASME thread system. The JBO Plug Gauges - UNC (STI) Wire Inserts are precision measuring tools designed to verify UNC STI thread inserts, enabling efficient inspection of inserts and confirmation that they meet defined standards. The plug gauge enables direct measurement of the pitch diameter to ensure correct fit and reliable performance of threaded inserts.

• DAkkS-calibrated for traceable accuracy: Ensures measurements are internationally recognized and auditable, reducing guesswork and easing quality-system compliance.
• Right-hand, 2B, No. 6 x 40 sizing: Tailored for UNC/STI insert geometries, providing fast, repeatable checks with clear, consistent readings in busy inspection workflows.
• Durable, ergonomic construction: Knurled body with robust metal ends delivers a comfortable grip, long life in shop environments, and reliable performance over time.

By using this plug gauge, you gain quick, dependable verification of insert pitch diameter, helping to minimize rework, speed up quality checks, and maintain consistent results across production runs. Its calibration and durable design provide confidence in your measurement process and alignment with industry standards.
