FANAR M6 6H Go/No-Go kierrekiertotulkki metrinen ISO-kierre

The FANAR M6 6H Go/No-Go Thread Plug Gauge is a precision measuring tool designed for checking internal metric threads (nuts) according to ISO 1502 and DIN 2244 standards. Manufactured from high-grade tool steel with a hardness of 60-62 HRC, this double-ended gauge features a Go end and a No-Go end for quick pass/fail inspection of M6 threads with 1.0 mm pitch and 6H tolerance class.

Advantages

Double-ended design saves time by combining Go and No-Go functions in one tool. Precision lapped surface finish ensures accurate and repeatable measurements. Knurled cylindrical handle provides a secure grip. Supplied in a protective plastic tube for safe storage and transport. Traceable calibration certificate available upon request.

Recommendations

For best results, keep the gauge clean and lightly oiled. Recalibrate periodically according to your quality management system. Always use the Go end first; if it does not enter the thread, the part is rejected. Then use the No-Go end; if it enters, the part is rejected.
