The JBO Plug Gauge for UNC (STI) wire inserts is a precision measuring tool designed to verify pitch diameter and confirm conformance of threaded inserts across critical industries. In its right-hand configuration, 2B class, and No. 10 x 32 size, this gauge supports accurate inspection of helicoil/STI inserts, helping you ensure proper fit and reliable performance. Calibrated to DAkkS standards and aligned with ANSI/ASME thread system specifications, it provides traceable measurements you can trust in production and QA audits.

• DAkkS-calibrated for traceable accuracy: The gauge ships with DAkkS calibration, delivering verifiable, audit-ready measurements that align with international standards.
• Pitch diameter verification for reliable inserts: Precisely checks pitch diameter to ensure UNC STI inserts fit correctly, reducing assembly issues and downtime.
• Durable, shop-ready construction: Rugged, machined design with a grippy knurled body stands up to daily use while maintaining long-term accuracy.

Used by engineers, quality inspectors, and shop floor technicians, this plug gauge speeds up inspection routines, enhances consistency across parts, and supports confident decisions during manufacturing and assembly. Its calibrated accuracy and durable build help you maintain tight tolerances, minimize rework, and meet stringent quality requirements with every measurement.
