Vermont Gage 361117510 Threaded Ring Gage 8-32 Unc

Product Description

The VERMONT GAGE 361117510 is a Go-type threaded ring gage machined from tool steel for dimensional inspection of external threads. It is designed to verify that a threaded fastener or component falls within the acceptable tolerance range for 8-32 UNC Class 2A threads. When the Go ring passes over the threaded part without interference, the thread form, pitch diameter, and lead are confirmed within specification. This gage is used by machinists, quality technicians, and inspection personnel working to NIST-traceable standards in production and receiving environments.

This gage is applied in quality control and manufacturing inspection wherever 8-32 UNC external threads must be verified against Class 2A tolerance limits. Class 2A is the most common fit class for general-purpose inch-series fasteners and threaded components. Typical applications include incoming inspection of fasteners, in-process thread verification on screw machine parts, and final inspection of assemblies requiring controlled thread fit. The single-ring Go design is used in conjunction with a separate No-Go gage when full tolerance verification is required.

Key Features

• Go-type ring gage confirms minimum material condition acceptance for 8-32 UNC Class 2A external threads
• Tool steel construction provides wear resistance for repeated use in production inspection environments
• Single-ring design allows dedicated Go or No-Go use within a two-gage inspection system
• Manufactured and traceable to NIST standards for reliable, auditable measurement results
• UNC thread form covers the most widely used inch-series coarse-pitch thread standard

Compatibility

Designed for inspection of external 8-32 UNC Class 2A threaded components, including fasteners, screws, and machined parts conforming to inch-series coarse-pitch thread standards.

Installation Notes

Threaded ring gages are handled and applied by quality control technicians and machinists, not installed in a system. Store the gage in a protective case away from other metal tooling to prevent nicking the thread form. Handle with clean, dry hands or gloves to prevent corrosion on the tool steel surfaces. Calibration and setting of adjustable ring gages, where applicable, should be performed by qualified metrology personnel using a certified setting plug.
