The JBO Plug Gauge - UNC (STI) Right Hand - 2B - No. 8 x 32, Calibrated (DAkkS Calibration) is a precision tool designed for inspecting UNC thread inserts (STIs). It’s built to verify the pitch diameter and confirm proper fit and function of threaded inserts, with ANSI/ASME thread standards guiding its design for dependable measurements across manufacturing, automotive, and aerospace environments.

  • DAkkS-Calibrated for traceable accuracy: DAkkS calibration provides official traceability of pitch-diameter measurements, supporting quality audits and consistent decision‑making on the shop floor.
  • UNC STI compatibility for precise insert verification: Specifically engineered for UNC STI wire inserts, it enables repeatable pitch-diameter checks to confirm correct fit and reliable performance.
  • Right-Hand, 2B tolerance with durable, user-friendly design: The right-hand orientation and 2B tolerance class set clear limits, while the rugged, knurled body offers a secure grip for fast, repeatable checks in busy environments.

This plug gauge helps streamline inspections by delivering fast, reliable pitch-diameter verification, reducing guesswork and rework. With DAkkS calibration and ANSI/ASME‑compliant design, you can trust results for audits and customer inspections. Its compact, two-ended form fits easily into standard gauge kits and workstations, supporting consistent measurements across teams and shifts. By validating UNC STI insert dimensions at the point of assembly, you’ll improve fit, reliability, and overall workflow in manufacturing, automotive, and aerospace applications.
