Description
The Truthread Thread Ring Gauge (NoGo) for UNEF right-hand threads is a precision tool designed to verify UN thread sizes with confidence. Sized for 9/16x24 UNEF and a 2A tolerance class, this NoGo gauge is calibrated to ensure the thread remains within tolerance by checking the minimum material condition. It’s ideal for verifying threaded parts that must not be larger than the maximum allowable size, making it a reliable choice for quality control in machining, assembly, and inspection workflows.
- UN Thread-Specific Calibration: Precisely gauges UN threads to confirm the thread is within tolerance, delivering dependable pass/fail results for production parts.
- NOGO Check for Minimum Material Condition: Verifies the lower limit of size so parts stay within allowable bounds and do not exceed the maximum size.
- Right-Hand UNEF Size 9/16x24 with 2A Fit: Matched to standard right‑hand UNEF threads and the 2A class, ensuring consistent, straightforward measurements and quick setup.
Used in daily QA and production checks, this gauge helps you accelerate inspections without sacrificing accuracy. By focusing on the critical minimum material condition for UN threads, it reduces rework, speeds decision-making, and supports reliable, repeatable results across batches and assemblies.
