Vermont Gage 362120020 Threaded Ring Gage M8x1 Class 6G No Go

Product Description

The VERMONT GAGE 362120020 is a single-ring No Go threaded ring gage used to verify that an external metric thread does not exceed its maximum material condition limit. Manufactured from tool steel, this gage checks M8 x 1.00 metric threads to Class 6G tolerance, ensuring threads that pass inspection fall within the specified dimensional limits. NIST traceability certification is included, supporting quality-management and calibration documentation requirements. Machinists, quality control technicians, and precision tooling shops use this gage as part of a go/no-go inspection routine on threaded fasteners, bolts, and threaded components.

This gage is suited for production inspection and receiving inspection environments where M8 x 1.00 metric external threads must be verified to Class 6G tolerance. Class 6G is a standard medium-tolerance fit widely used in general-purpose metric fastener applications. The No Go member confirms the thread pitch diameter does not exceed the upper tolerance boundary. It is used as the rejection member of a two-gage set alongside a corresponding Go ring gage.

Key Features

• No Go ring gage for M8 x 1.00 metric external threads to Class 6G tolerance
• Single-ring design for dedicated No Go inspection use
• Tool steel construction for durability and wear resistance in production environments
• NIST traceability certification included for calibration and quality documentation
• UNSPSC Code 41111619 for procurement system classification

Compatibility

Designed for inspection of M8 x 1.00 metric externally threaded components manufactured to Class 6G tolerance specifications.

Installation Notes

Threaded ring gages are used by quality control technicians and machinists and require no permanent installation. Handle the gage carefully to avoid drops or impacts that can alter calibration. Store in a clean, dry environment and keep free of chips, coolant, and debris before and after use. Periodic re-calibration against a traceable standard is recommended to maintain measurement integrity.
