Balax 90570-000 Plug Thread Gage 00-90 Single End Go

Product Description

The BALAX 90570-000 is a single-end Go plug thread gage designed to verify the minimum material condition of internal threads. Machined from high speed tool steel with a bright finish, this gage checks the Go pitch diameter of 00-90 unified threads, confirming that a threaded hole will accept a mating fastener within tolerance. The Go pitch diameter is 0.0398 inches. Overall length is 1.625 inches. A handle is not included, so the gage is used with a standard gage handle purchased separately. Machinists, toolroom technicians, and quality control inspectors use this gage for precision thread verification on small-diameter internal threads.

This plug thread gage is suited for inspection and quality assurance operations in machine shops, manufacturing facilities, and precision assembly environments. It is intended for use on 00-90 threaded holes where conformance to thread tolerance must be confirmed before assembly. The single-end Go configuration allows efficient pass or fail verification on the minimum acceptance condition of the thread. It is well suited to applications involving miniature fasteners in instrumentation, optics, and fine-pitch mechanical assemblies.

Key Features

• Go-type single-end design checks minimum material condition of internal 00-90 threads
• Go pitch diameter of 0.0398 inches for 00-90 thread size
• High speed tool steel construction for wear resistance and dimensional stability
• Bright finish for easy visual inspection of the gage surface
• Overall length of 1.625 inches for use with standard gage handles
• Metric standards classification

Compatibility

Designed for verifying 00-90 internal threaded holes. Compatible with standard plug gage handles that accept the appropriate gage shank diameter for this size class.

Installation Notes

Thread plug gages are handled by quality control technicians and toolroom personnel following standard metrology practices. Ensure the threaded hole is clean and free of chips or debris before gaging. Apply light hand pressure only when inserting the Go gage - do not force the gage through a hole that resists entry, as this can damage the gage or the part. Store gages in a protective case away from other tooling to prevent nicking the precision ground surfaces.
