The Asimeto Ring Thread Gauge (Go/NoGo) in Imperial size is a precision tool for machinists, quality-control professionals, and workshop technicians who need fast, reliable verification of external threads. Conforming to ASMEB1.20.1-2013 and sized for right-hand 1/8 x 27 threads, it provides consistent depth and tolerance checks for accurate, repeatable results.

• Size and standard: Imperial 1/8 x 27 Go/NoGo ring gauge, designed to ASMEB1.20.1-2013 specifications.
• Design: 3-step L3 configuration that delivers precise verification of thread depth and engagement.
• Right-hand threading: Calibrated specifically for right-hand external threads common in fasteners.
• Go/NoGo functionality: Dual check for quick pass/fail assessment, streamlining inspection workflows.
• Quality-control application: Ideal for incoming, in-process, and final inspections in machining and manufacturing environments.

With this gauge, you gain a dependable method to verify external threads against a defined standard. The Go step confirms full engagement depth, while the NoGo step ensures threads do not exceed tolerance, helping prevent cross-threading and misfits. The 3-step L3 profile delivers repeatable results across parts, supporting tighter quality control, reduced rework, and more efficient production cycles in turning, milling, and assembly operations.
