The Asimeto Plug Thread Gauge (D/E) is a precision right-hand go/no-go gauge designed to quickly verify 3/8-16 UNC internal threads in holes. Built for machinists, inspectors, and maintenance professionals, it delivers reliable checks for UNC, UNF, and UNEF thread standards.

• Size & Tolerance: 3/8-16 UNC, right-hand thread, 2B tolerance class for consistent, repeatable measurements.
• Thread Standards: Compatible with UNC/UNF/UNEF internal threads to cover common manufacturing and assembly needs.
• Material & Finish: Made from high-quality steel with a durable finish to withstand daily shop use and maintain accuracy.
• Tapered Design: Tapered tip with a knurled handle provides easy insertion into threaded holes and stable handling during checks.
• Go/No-Go Precision: Calibrated to deliver reliable go/no-go assessments, helping you confirm proper thread form and fit at a glance.
• Series & Construction: Part of the Asimeto 695 Series, engineered for precision tools that support consistent measurement standards.

Using this gauge speeds up quality control and assembly workflows by confirming that internal threads are clean, correctly formed, and within tolerance. Its robust construction supports daily use in machining, fabrication, and maintenance environments, while the tapered insertion and clear design reduce the risk of cross-threading and measurement variability.
