The JBO Plug Gauge is a precision metric plug gauge designed to verify metric screw thread inserts (STIs). Sized for M16 x 1.5 right-hand threads and finished for metric fine (STI) applications, it supports fast, reliable inspections in manufacturing, automotive, and aerospace environments.

Manufactured and assessed in accordance with ANSI/ASME thread standards, this Helicoil gauge delivers tight dimensional control and dependable performance. It is DAkkS-calibrated to provide traceable, auditable measurement results across quality systems.

• DAkkS-calibrated for traceable accuracy: Ensures measurement results are directly linked to international standards, supporting compliant quality records and audits.
• M16 x 1.5 metric STI compatibility (Right-Hand): Precisely matched to the intended insert size and threading direction, reducing guesswork during inspection and ensuring correct fit checks.
• Durable knurled body with easy handling: Robust construction and a textured grip enable repeated use in busy shop environments, improving reliability and tool life.

With its precise calibration, STI-specific sizing, and rugged construction, the JBO Plug Gauge helps you streamline threaded-insert inspections, shorten setup times, and deliver consistent, repeatable results across critical production processes.
