Description
Truthread Thread Ring Gauge (NoGo) for UNEF right-hand threads is a precision inspection tool designed to verify UN thread size and tolerance. Specifically sized for 1-7/16 x 18 UNEF, 2A class, it helps machinists, inspectors, and quality teams quickly confirm parts meet the lower limit of the allowable size.
Designed for UNEF right-hand threads (2A) at 1-7/16 x 18, this NoGo gauge is calibrated to ensure that the thread is within tolerance. The NoGo gauge checks the minimum material condition of the part, ensuring that it is within the lower limit of the allowable size, making it ideal for measurements where parts must not be larger than the maximum allowable size.
- NoGo verification for UNEF right-hand 2A threads: Confirms the threaded part stays within the lower limit of size, helping prevent undersized components and reducing scrap.
- Precise calibration for UN thread tolerance: Delivers repeatable, accurate results across operators and production runs, reducing measurement guesswork.
- Rugged, knurled ring design for easy handling: Provides secure grip and quick alignment in busy workshops, supporting fast, reliable checks.
Using the Truthread NoGo gauge streamlines quality control by delivering fast, dependable pass/fail decisions on UN threaded parts. It helps you maintain consistent fits across batches, lowers rework, and supports more efficient inspection cycles in machining, assembly, and supplier qualification processes.
