Osg 1500200600LF Plug Thread Gage M6x1.00 6H Class

Product Description

The OSG 1500200600LF is a double-end plug thread gage designed to verify M6x1.00 internal threads to the 6H tolerance class. The Go end checks that the thread falls within the minimum material condition, while the No Go end confirms the thread has not exceeded the maximum material limit. The Go pitch diameter is 5.35 mm and the No Go pitch diameter is 5.50 mm. Constructed from high speed steel for wear resistance and dimensional stability, this gage is used by machinists, quality control technicians, and tool room personnel to confirm thread conformance on machined parts and assemblies.

This gage is suited for production inspection and incoming quality control in machine shops, manufacturing facilities, and precision fabrication environments. It applies to M6x1.00 threaded holes in metal components where 6H class thread fit is specified. The double-end design consolidates both Go and No Go functions into a single tool, reducing bench clutter and handling time during inspection routines. A handle is included, and a NIST traceability certification is provided with the gage to support documented quality systems.

Key Features

• Double-end design with Go and No Go on a single gage body
• Go pitch diameter: 5.35 mm for minimum material condition verification
• No Go pitch diameter: 5.50 mm for maximum material limit verification
• High speed steel construction for dimensional stability and extended service life
• Includes handle for secure, repeatable hand use during inspection
• NIST traceability certification included to support ISO and quality documentation requirements

Compatibility

Designed for inspection of M6x1.00 internal threads conforming to the 6H tolerance class per applicable thread standards.

Installation Notes

Thread gages are inspection tools and do not require installation in the mechanical sense. Handle the gage carefully to avoid dropping or striking the precision ground ends, as impact damage will affect calibration. Clean threads and gage members before use to prevent false readings. Store the gage in its protective case when not in use to maintain calibration integrity, and re-certify on a schedule consistent with your quality management system requirements.
