Emuge L0200500.5062 Ring Gage 1/2-28 Unef 2A Go

Product Description

The EMUGE L0200500.5062 is a Go-type threaded ring gage used to verify the maximum material condition of external threads. Manufactured from tool steel and built to DIN 2285 standards, this single-ring gage checks 1/2-28 UNEF Class 2A threaded workpieces for conformance to tolerance requirements. A Go gage must pass fully over the thread being inspected - if it does not, the workpiece is out of tolerance on the high side. This gage is used by machinists, quality control inspectors, and precision tooling professionals in production and inspection environments where thread accuracy is critical.

This gage is suited for inspecting external 1/2-28 UNEF threads on fasteners, fittings, and machined components held to Class 2A tolerances. Class 2A is the most common tolerance class for general-purpose inch-series threaded fasteners, making this gage widely applicable across manufacturing, aerospace, automotive, and fluid-system component inspection workflows. It is a single-ring design, used independently as the Go member of a Go/No-Go inspection pair.

Key Features

• Go-type gage verifies maximum material condition on external 1/2-28 UNEF threads
• Tool steel construction for wear resistance and dimensional stability
• Manufactured to DIN 2285 standards for gage geometry and tolerancing
• Single-ring design - used as the Go member in a two-gage inspection set
• Class 2A tolerance class matches the most common general-purpose fastener specification

Compatibility

Designed for inspection of external 1/2-28 UNEF Class 2A threaded components. Compatible with any workpiece requiring Go-gage verification to UNEF thread form standards at this size and tolerance class.

Installation Notes

Threaded ring gages are used by quality inspectors and machinists - no installation in a mechanical system is required. Store the gage in a protective case and keep it away from chips, coolant, and abrasive surfaces to preserve calibration. Handle with clean, dry hands or inspection gloves to prevent corrosion from skin oils. Gages should be periodically recalibrated or inspected against a master setting plug per your facility quality plan.
