Truthread Thread Ring Gauge (NoGo) - UNEF - Right Hand - 2A - 1x20

Truthread Thread Ring Gauge (NoGo) - UNEF - Right Hand - 2A - 1x20 is a precision tool designed to verify external UNEF threads against standard size limits. Calibrated to ensure the thread is within tolerance, it provides quick, reliable validation of parts that must meet exact specifications.

Ideal for machinists, inspectors, and maintenance technicians, this NoGo gauge checks the minimum material condition—ensuring the threaded part stays within the lower limit of the allowable size. It’s particularly useful for identifying parts that should not be larger than the maximum size, helping you prevent undersized components from passing QC.

• UNEF 2A Right-Hand design: Tailored for UNEF external threads with the correct hand and tolerance class, delivering consistent engagement and repeatable results.
• Calibrated for UN thread tolerance: Precisely calibrated to verify the thread remains within the defined tolerance, ensuring dependable measurements across operators and jobs.
• NoGo minimum material check with knurled grip: Validates the lower size limit to prevent undersized parts from passing, while the knurled edge enables secure handling even with work gloves.

This gauge supports streamlined quality control by delivering fast, confidence-building checks on threaded components. Use it on the shop floor to reduce rework, speed up inspections, and maintain consistent results across production runs.
