The Asimeto Ring Thread Gauge (Go/NoGo) in Imperial sizes is a precision inspection tool for external threads. It’s ideal for engineers, machinists, quality inspectors, and shop floor personnel who need a reliable check on thread accuracy during machining and assembly.

These right-handed gauges conform to ASMEB1.20.1-2013 standards and feature a 3-step L3 design to verify thread depth and tolerance quickly and consistently.

• 3‑Step L3 design for precise verification: The three-step geometry provides a clear, repeatable reference for checking thread depth and tolerance across imperial sizes, helping detect under- or over-tolerance conditions with confidence.
• Go/NoGo measurement for fast, confident passes: Quick pass/fail results reduce inspection time and minimize ambiguity, keeping production moving and ensuring consistent results.
• Imperial, right‑hand gauge aligned to ASMEB1.20.1-2013: Ensures compatibility with common imperial thread forms and supports reliable quality control across parts and processes.

Using this gauge helps you quickly verify external thread accuracy, reducing trial-and-error adjustments and preventing misfitted fasteners. The Go/NoGo method delivers clear, repeatable results that speed up setup, lower downtime, and improve overall quality in machining and manufacturing workflows.
