The Asimeto Plug Thread Gauge (D/E) is a compact, precision tool designed to quickly verify internal metric threads. Built for machinists, quality-control technicians, and assembly engineers, it delivers reliable go/no-go checks for small components with M3 x 0.5 coarse threads.

• Thread size: M3 x 0.5 metric coarse pitch, right-hand orientation for standard internal threading checks.
• Gauge class: 6H internal thread tolerance class to ensure consistent acceptance limits across parts.
• End design: Dual ends (D/E) provide testing convenience for measuring engagement at multiple depths on a single gauge.
• Series and construction: Part of the 680 Series, engineered for durable, repeatable performance in demanding environments.
• Material and finish: Crafted from high-quality materials with a robust working finish for everyday workshop use.
• Portability and usability: Compact, easy-to-handle gauge that fits into standard tool kits for on-the-spot verification.

This gauge helps you confirm that internal threads meet specification, reducing assembly guesswork and minimizing the risk of misfit parts. By delivering quick, reliable checks for M3 x 0.5 holes, it speeds up setup, calibration, and quality-control workflows while supporting consistent part quality across production runs.
