RUKO SCE-DIN223-MF7x0.75mm Metric Fine Thread Plug Gauge GO/NO-GO 6H

This RUKO thread plug gauge is built for precision verification of metric fine internal threads with a nominal diameter of 7 mm and a pitch of 0.75 mm. The double-ended GO/NO-GO design allows quick pass/fail inspection in one tool, eliminating the need for separate gauges. Conforming to DIN 223 (ISO 1502) and tolerance class 6H, it is suited for production environments where consistent thread quality is critical.

Highlights

• Metric fine thread: M7 × 0.75
• Tolerance class: 6H
• Double-ended GO/NO-GO gauge
• High-grade gauge steel, hardened and ground
• Lapped surface for accuracy and corrosion resistance

In daily use

The gauge features a cylindrical handle with knurled grip for secure handling. The GO end checks the minimum material limit, while the NO-GO end checks the maximum material limit. Factory calibrated and ready for immediate use in quality control, machining, or maintenance tasks.
