Balax 90538-000 M1.00 X 0.250 Thread Go No Go Gage Set

Product Description

The BALAX 90538-000 is a 2-piece miniature plug thread Go/No Go gage set designed to verify internal thread conformance on M1.00 x 0.250 metric threads. Manufactured from high speed tool steel with a bright coating, this set delivers the dimensional stability required for precise thread inspection in small-bore applications. The Go member checks minimum material condition at a pitch diameter of 0.84 mm (0.0331 inches), while the No Go member checks maximum material condition at a pitch diameter of 0.0341 inches. A handle is included with the set. This gage is used by machinists, quality control technicians, and tool and die professionals working to metric thread standards.

This gage set is suited for inspecting M1.00 x 0.250 miniature metric threads in precision machining, electronics manufacturing, medical device fabrication, and other industries where small-diameter threaded fasteners require verified conformance. The miniature classification makes it appropriate for components where standard-size gages cannot access the thread form. Both Go and No Go members are included, enabling a complete pass/fail check in a single set without sourcing members separately.

Key Features

• Go and No Go members included for complete minimum and maximum material condition verification
• High speed tool steel construction for dimensional stability and wear resistance
• Bright coating finish on both gage members
• Go pitch diameter: 0.84 mm
• No Go pitch diameter: 0.0341 inches
• Handle included - no additional handle purchase required

Compatibility

Designed for inspection of M1.00 x 0.250 miniature metric internal threads. Suitable for use wherever that thread form and size must be verified to Go/No Go acceptance criteria.

Installation Notes

Thread gages are installed and used by machinists or quality control inspectors - no power shutdown is required for gage use. Apply light machine oil to the gage members before use to reduce wear and protect the thread form. Never force a Go or No Go gage; if the Go member does not pass freely or the No Go member enters the thread, evaluate the workpiece against applicable thread tolerance standards. Store gage members in a protective case away from other tooling to prevent contact damage to the thread form.
