Description
Truthread Thread Ring Gauge (NoGo) for UNF threads is a precision inspection tool designed to verify threaded components against UNF standards. Built for a wide audience—from engineers and QA inspectors to machinists and shop technicians—it delivers quick, reliable checks that keep assemblies moving smoothly.
Calibrated to ensure the thread is within tolerance, this NoGo gauge checks the minimum material condition, confirming the part remains within the lower limit of the allowable size. It’s ideal for identifying parts that must not be larger than the maximum allowable size. Size: 1-1/4 x 12 UNF, Right Hand, 2A (Class 2A) tolerance.
- UNF-specific calibration: Precisely calibrated for UNF threads to deliver accurate, repeatable tolerance checks every time.
- NoGo minimum material verification: Verifies the lower-limit condition of the thread so undersized parts are caught early and rejects out-of-spec components.
- Rugged, easy-to-handle design: Knurled outer edge provides a secure grip and quick, confident alignment for fast inspections, even in busy work environments.
Using the Truthread NoGo gauge simplifies quality control by giving you a clear pass/fail result for each threaded part. It helps reduce rework, speeds up inspection cycles, and supports consistent results across batches, so you can trust your measurements and keep production on schedule.
