Balax 90497-000 Sti Plug Thread Insert Go No Go Gage 6-32

Product Description

The BALAX 90497-000 is a double-ended STI plug thread insert Go/No Go gage designed for inspecting 6-32 threaded inserts to Class 3B tolerances. Manufactured from high speed tool steel, this gage delivers the hardness and dimensional stability required for repetitive inspection work on the shop floor or in the field. The double-ended design integrates both the Go and No Go members into a single tool, reducing changeover time during inspection. A handle is included, providing a consistent grip and helping technicians apply controlled, repeatable axial force. This gage conforms to ANSI standards for thread gaging and is suited for quality control personnel, machinists, and maintenance technicians working with helical coil or screw thread inserts.

This gage is used to verify that 6-32 STI threaded insert installations meet Class 3B fit requirements. Typical applications include acceptance inspection of threaded inserts in aerospace, industrial, and general manufacturing environments where insert threads are used to restore or reinforce tapped holes. It is appropriate for use in production inspection, incoming quality checks, and post-installation verification of thread insert integrity.

Key Features

• Double-ended design incorporates both Go and No Go members in one tool
• High speed tool steel construction provides hardness and wear resistance for sustained inspection use
• Class 3B classification ensures inspection to tight tolerance thread fit requirements
• Conforms to ANSI thread gaging standards
• Handle included for controlled grip and consistent axial load during gaging
• Designed specifically for STI (Screw Thread Insert) thread form inspection

Compatibility

Designed for inspection of 6-32 STI threaded inserts held to Class 3B tolerances. Verify thread form and insert specification before use to confirm gage applicability.

Installation Notes

Thread gages are inspection tools, not cutting or forming tools - do not force the gage through a thread under resistance. Ensure the threaded insert is fully seated and free of chips or debris before gaging. Store the gage in its protective case when not in use to prevent damage to the precision ground members. Periodic calibration against certified setting masters is recommended to maintain measurement traceability.
