The JBO Thread Ring Gauge (GO) for UNF Right-Hand threads, No. 8 x 36 (2A), is a compact go/no-go tool designed for fast, accurate exterior thread checks. It’s ideal for engineers, machinists, quality inspectors, and assembly teams who need to confirm that threaded parts meet minimum size before mating with fasteners or components. The gauge’s knurled outer edge provides a secure grip for quick testing in busy work environments.

Built from hardened steel and finished for durability, this GO gauge delivers long-lasting performance in demanding shop conditions. Its precise dimensions support reliable identifications of compliant parts, helping teams reduce rework and keep production flowing smoothly.

• Precise UNF Right-Hand GO gauge (No. 8 x 36, 2A): Enables fast pass/fail checks to verify minimum external thread size, ensuring parts fit correctly with mating components.
• Hardened steel construction: Resists wear and maintains calibration over time, delivering consistent results in daily use.
• User-friendly, repeatable inspections: Simple, intuitive operation that speeds setup and delivers dependable, repeatable results across operators and shifts.

Using the JBO Thread Ring Gauge helps you streamline quality control, reduce inspection time, and improve overall assembly reliability by ensuring every No. 8 UNF right-hand threaded part meets the required standard before it’s placed into production or into service.
