JBO Plug Gauge - UNF (STI) Heli Coil Gauge - Right Hand - 2B - No. 8 x 36 - Calibrated (DAkkS Calibration)

The JBO Plug Gauge for UNC (STI) Wire Inserts is a precision measuring tool designed to verify the pitch diameter of screw thread inserts (STIs). Manufactured and assessed to ANSI / ASME thread standards, this gauge carries DAkkS calibration for traceable, verifiable measurements across production and inspection environments.

Designed for use on shop floors, quality labs, and in high-stakes manufacturing contexts, it provides fast, repeatable checks to confirm UNC STI inserts meet specification and perform reliably in critical assemblies. This gauge helps inspection teams verify fitment quickly, supporting consistent quality in automotive, aerospace, and general manufacturing applications.

• DAkkS-calibrated traceability: Delivers certified, standards-backed dimensions that support audit-ready quality control and long-term measurement reliability.
• Pitch diameter verification for UNC (STI) inserts: Enables direct, accurate assessment of pitch diameter to ensure proper fit and dependable insert performance.
• Rugged, precise construction with a knurled grip: Built for demanding environments, providing secure handling and durable, repeatable measurements over many cycles.

This gauge streamlines your workflow by delivering clear, trustworthy measurements that teams can rely on for consistent results. With ANSI/ASME compliance and DAkkS calibration, you can trust every reading to reflect true insert dimensions, helping you reduce rework, accelerate inspections, and maintain high-quality threaded assemblies across projects.
