The Asimeto Plug Gauge from the 682 Series is a precision inspection tool designed to verify internal threads on metric fine fasteners. It’s built for machinists, quality control professionals, and assembly engineers who need fast, reliable checks of thread pitch diameter to ensure parts fit correctly.

• Series and tolerance: 682 Series plug gauge designed to 6H tolerance for accurate verification of internal metric threads.
• Thread size and orientation: M39 x 3, right-hand thread, aligned with standard metric practice for fine-fastener applications.
• Construction and durability: Precisely machined ends on a rugged cylindrical body with a knurled grip for secure handling; crafted from high-quality materials to withstand repeated use.
• Measurement capability: Reads the pitch diameter of internal threads to confirm conformity with specification, enabling quick pass/fail decisions.
• Ease of use: Simple plug-gauge design that slides into the threaded hole to verify fit without complex setup or equipment.

This gauge excels in in-process inspection on CNC or manual machines, incoming quality control for supplied fasteners, and routine maintenance checks on threaded assemblies. With its strict 6H class conformity, it helps ensure metric threads are within tolerance, reducing rework and counterfeit risks while supporting consistent, reliable assembly across production runs. Use it to validate thread engagement, calibrate other thread gauges, and provide precise documentation of thread quality for audits and customer requirements.
