The Asimeto 682 Series Thread Plug Gauge (D/E) is a precision Go/No-Go tool designed to quickly verify metric internal threads. Built for M4 x 0.5 right-hand threads and 6H tolerance, it helps machining, QA, and maintenance teams confirm thread acceptability with confidence.

• Go/No-Go ends on a single handle: Dual ends provide an immediate pass/fail check, with the No-Go side clearly identified for fast interpretation.
• Thread designation: Metric fine thread M4 x 0.5, right-hand configuration.
• Tolerance: Conforms to 6H tolerance class, ensuring accurate pitch-diameter verification.
• Construction and finish: Made from high-quality gauge steel with a hardened finish and a cylindrical, knurled body for secure grip.
• Standards and dimensions: Dimensions follow DIN ISO 1502, with a 20°C reference temperature used for workpieces and gauges to maintain consistency.
• Identification: Red marking distinguishes the No-Go side, reducing reading ambiguity during inspection.
• Applications: Ideal for quick thread inspection on the shop floor, in quality control, and during routine maintenance where M4 x 0.5 threads are used.

With the Asimeto 682 Series plug gauge, you gain a fast, repeatable method to assess thread acceptance. The dual-end Go/No-Go design provides a clear decision without complex measurement, while the robust construction supports long-term accuracy under routine use. This gauge helps standardize inspections across operators and shifts, supporting consistent fastener performance.
