Vermont Gage 361147010 Threaded Ring Gage 5/8-11 Unc

Product Description

The VERMONT GAGE 361147010 is a single-ring threaded ring gage used to verify the external thread dimensions of fasteners and threaded components. Classified as a Go gage to the Class 2A tolerance standard, it confirms that a threaded part falls within the acceptable dimensional range for fit and function. Machined from tool steel and calibrated to NIST standards, this gage is built for repeated use in production and inspection environments. It is a standard tool for quality control technicians, machinists, and inspectors working with inch-series threaded fasteners.

This gage is suited for inspection of 5/8-11 UNC external threads in both shop floor and receiving inspection applications. The Class 2A designation covers the most common tolerance class for general-purpose inch-series fasteners, making this gage widely applicable across manufacturing, maintenance, and assembly operations. It is used in facilities that require documented thread verification as part of their quality management process.

Key Features

• Go classification confirms external threads meet the lower boundary of Class 2A tolerance
• 5/8-11 UNC thread size for standard inch-series fastener inspection
• Single-ring design for straightforward Go verification
• Tool steel construction for durability and dimensional stability under repeated use
• Calibrated to NIST standards for traceable measurement compliance

Compatibility

Designed for inspection of 5/8-11 UNC external threads conforming to Class 2A tolerance requirements per inch-series thread standards.

Installation Notes

Threaded ring gages are handled and applied by quality control technicians and machinists during inspection operations. Keep gages clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the gage onto a thread; the Go gage should advance freely under hand pressure alone. Store in a protective case away from impact and temperature extremes to preserve calibration integrity.
