The Asimeto Plug Gauge (D/E) in the 682 Series is a precision tool for quick, reliable verification of internal metric threads on fine-fastener components. Designed for machinists, inspectors, and manufacturing teams working with metric fasteners, it provides accurate pitch-diameter checks that align with standard industry tolerances.

• Series and purpose: 682 Series plug gauges crafted for measuring and verifying metric internal threads on precision fasteners.
• Tolerance: Conforms to 6H tolerance class to ensure consistent, reliable measurements of the thread pitch diameter.
• Thread size: M4 x 0.35 metric fine thread, designed to match the tested component’s specifications.
• Right-hand design: Optimized for standard right-handed thread systems used in common fasteners.
• Construction: Cylindrical body with a textured grip and precisely machined ends that correspond to the specified thread size.
• Material and durability: Manufactured with high-quality materials to withstand regular use and provide stable measurements over time.
• Applications: Ideal for quick internal-thread checks during incoming inspection, in-process quality control, and routine maintenance in machining and assembly environments.

The plug gauge delivers fast, repeatable verification of internal threads, helping you confirm that M4 x 0.35 threads meet the 6H specification before parts move to assembly or further processing. Its robust construction supports daily shop-floor use, while the precise ends ensure accurate assessment of thread engagement and pitch diameter. Whether you’re validating new components or performing routine quality checks, this gauge provides a dependable, easy-to-interpret measurement reference that supports consistent part fit and reduced rework.
