The EMUGE L0200501.0080 is a single-ring threaded ring gage used to verify the external thread tolerance of M8 x 1.25 metric fasteners and threaded components. This is the Go gage of the pair, designed to pass over a correctly formed thread with minimal resistance, confirming that the thread pitch diameter and form fall within the upper boundary of Class 6H tolerance. Manufactured from tool steel and built to DIN ISO 1502 standards, this gage delivers the dimensional consistency required for production inspection and incoming quality control. Machinists, tool room technicians, and quality inspectors rely on this type of gage for thread verification in both shop floor and inspection environments.
This gage is suited for inspecting M8 x 1.25 external threads on bolts, studs, threaded shafts, and machined parts in metric thread applications. Class 6H is the standard general-purpose tolerance class for metric internal threads, making this gage appropriate for high-volume production environments where compliance with metric thread standards is required. It is commonly used in manufacturing, aerospace component inspection, automotive assembly, and general machining operations where consistent thread quality must be verified before assembly.
Designed for inspection of M8 x 1.25 external metric threads classified to Class 6H tolerance per DIN ISO 1502. Compatible with any externally threaded component using that thread form and tolerance class.
Thread ring gages are handled and used by machinists, quality technicians, and inspection personnel - no installation in a mechanical system is required. Store the gage in a clean, dry environment to prevent corrosion and protect the thread form. Do not force the gage onto a thread; resistance during the Go check indicates the thread is out of tolerance and the gage should be removed without applying additional torque. Periodic calibration against a master setting plug is recommended to maintain measurement integrity over time.
