Osg 1500202600 Plug Thread Gage M24x1.5 6H Double End

Product Description

The OSG 1500202600 is a double-end plug thread gage designed to verify internal M24x1.5 threads to the 6H tolerance class. One end serves as the Go gage to confirm minimum material condition, while the No Go end checks the maximum material condition, ensuring threads fall within specification. The gage body is manufactured from high speed steel for wear resistance and dimensional stability under repeated use. A handle is included. This type of gage is a standard tool in quality control and machining environments where threaded hole acceptance must be documented before assembly.

This gage is used to inspect M24x1.5 fine-pitch internal threads in production machining, maintenance repair, and incoming inspection settings. Typical applications include checking tapped holes in automotive, aerospace, hydraulic, and general industrial components. The double-end design keeps both Go and No Go elements in a single assembly, reducing handling time during inspection. Machinists, quality technicians, and tool crib personnel are the primary users.

Key Features

• Double-end design combines Go and No Go gages in one unit for efficient thread inspection
• M24x1.5 fine-pitch thread size for precise internal thread verification
• 6H classification ensures conformance to ISO metric thread tolerance standards
• High speed steel construction resists wear and maintains dimensional accuracy over extended use
• Handle included — no separate purchase required
• Compact overall length of 6 inches suits bench and floor inspection workflows

Compatibility

Designed for use with any tapped hole conforming to the M24x1.5 thread form at 6H tolerance class. Verify the thread specification of the workpiece before use to confirm correct gage selection.

Installation Notes

Thread gages are precision measuring instruments and should be handled and stored with care to prevent damage to the gage members. Do not force the Go end through a threaded hole; hand-pressure entry only is correct practice. The No Go end should not enter more than two turns — entry beyond that indicates an out-of-tolerance condition requiring corrective action. Calibration intervals should follow the shop quality plan and applicable ISO or ASME gage standard requirements.
