The Asimeto 682 Series plug gauge is a precision tool for verifying internal metric threads on fine fasteners. Designed for machinists and quality-control technicians, it delivers reliable pitch-diameter checks for M40 x 1.5 right-hand threads within a 6H tolerance.

• Series: 682 Series plug gauge crafted to measure and verify internal metric threads with consistent accuracy.
• Thread Size and Orientation: Right-hand M40 x 1.5 gauge ends for direct engagement with internal threads.
• Tolerance: Conforms to 6H class to ensure precise pitch diameter measurement across standard metric threads.
• Construction and Grip: Cylindrical, knurled body with precision-machined ends for secure handling and easy alignment.
• Durability: Built from high-quality materials to endure daily workshop use and maintain accuracy over time.

Using this gauge, you can quickly confirm that internal threads meet specification, reducing guesswork during assembly and quality checks. The 6H tolerance helps identify undersize or oversized threads, preventing cross-threading and improving fastener performance. The knurled grip and robust design provide repeatable measurements even in tight workspaces or when wearing gloves, making it a dependable tool in manufacturing, machining, and maintenance tasks.
