Vermont Gage 302138030 Plug Thread Gage M16x2 6H Go No Go

Product Description

The VERMONT GAGE 302138030 is a double-end plug thread gage designed to verify M16x2 metric threads to the 6H tolerance class. One end checks the Go condition with a pitch diameter of 14.70 mm; the opposite end checks the No Go condition at 14.91 mm pitch diameter. The gage body is manufactured from tool steel for wear resistance and dimensional stability under repeated use. A handle is included and sized to fit standard handle size 3. Traceability certification to NIST standards is included with the unit, supporting quality-system documentation requirements in production and inspection environments.

This gage is used in machining, manufacturing, and assembly operations where M16x2 threaded holes must be verified for conformance before parts proceed to the next stage. It suits both shop-floor inspection and incoming quality control checks. The double-end configuration keeps both Go and No Go elements on a single tool, reducing changeover time during high-volume thread inspection. Machinists, quality technicians, and tool-room personnel are the primary users of this gage class.

Key Features

• Double-end design combines Go and No Go checks in one tool
• Go pitch diameter: 14.70 mm per 6H class specification
• No Go pitch diameter: 14.91 mm per 6H class specification
• Tool steel construction for durability and dimensional stability
• NIST traceability certification included for quality-system compliance
• Handle size 3 included — no separate handle purchase required

Compatibility

Designed for inspection of M16x2 metric internal threads manufactured to the 6H tolerance class.

Installation Notes

Thread plug gages require no installation but should be handled and stored per ASME B1.16M or applicable gage-calibration procedures. Inspect the gage for nicks or wear before each use; a damaged gage should be removed from service and recalibrated. Apply a light thread-gage lubricant when gauging to reduce wear and improve measurement consistency. Retain the NIST traceability certificate with your calibration records.
