Vermont Gage 362111520 Threaded Ring Gage M4x0.70 6G No Go

Product Description

The VERMONT GAGE 362111520 is a single-ring threaded ring gage used to inspect M4 x 0.70 metric external threads to Class 6G tolerance. It functions as the No Go member of a Go/No Go gage set, confirming that a threaded workpiece does not exceed the maximum material condition of the specified thread class. Machined from tool steel, the gage provides the hardness and dimensional stability required for repeatable inspection on the shop floor or in a quality lab. A NIST traceability certification is included, supporting ISO and QMS documentation requirements. This type of gage is a standard tool in thread inspection for fastener, machined component, and precision assembly work.

This gage is suited for inspecting M4 x 0.70 metric externally threaded parts in manufacturing, machining, and assembly environments. Typical applications include incoming inspection of threaded fasteners, in-process verification of turned or milled components, and final inspection before assembly. It is commonly used in job shops, production machining facilities, and quality control departments that maintain documented inspection processes. The single-ring design covers the No Go function only, making it appropriate for facilities that maintain separate Go and No Go gages per standard inspection practice.

Key Features

• No Go member for M4 x 0.70 metric thread inspection to Class 6G tolerance
• Single-ring construction dedicated to one inspection function
• Tool steel construction for hardness and long service life
• NIST traceability certification included for quality system documentation
• Metric thread form compatible with standard M4 x 0.70 externally threaded components

Compatibility

Designed for inspection of M4 x 0.70 metric external threads manufactured to Class 6G tolerance. Intended for use as the No Go gage in a standard two-gage thread inspection setup.

Installation Notes

Thread ring gages are handled and used by quality technicians and machinists performing thread inspection. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the gage onto a threaded part; a properly sized No Go gage should not engage a conforming thread. Store in a protective case away from impact, abrasive materials, and temperature extremes to preserve calibration integrity.
