Spi 29-932-1 Class Zz Plus Plug Gage 0.932 in

Product Description

The SPI 29-932-1 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal size of 0.932 inches. Built to Class ZZ Plus tolerances of 0.0002 inches, this gage provides a reliable go/no-go reference for quality control and inspection work in machine shops, manufacturing facilities, and maintenance environments. The steel construction delivers durability for repeated use in production settings. Metrology technicians, machinists, and quality control inspectors are the primary users of this tool.

This plug gage is suited for checking drilled, reamed, or bored holes in workpieces where dimensional accuracy is critical. It is commonly used in both job shop and production-floor inspection workflows. The 0.932-inch nominal diameter makes it appropriate for applications involving medium-bore components across general manufacturing and precision machining operations. It ships individually, making it a practical single-size addition to an existing gage set.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for accurate go/no-go inspection
• Nominal measurement diameter of 0.932 inches
• Steel construction for durability in production and inspection use
• Compact and lightweight at 0.2 pounds for easy hand use
• Single-piece packaging for individual size replacement or kit supplementation

Compatibility

Designed as an OEM-style replacement or supplemental gage for use in standard Class ZZ Plus plug gage sets and bore inspection applications requiring a 0.932-inch nominal diameter reference.

Installation Notes

Plug gages require no installation but should be handled and stored according to standard metrology practices. Clean the gage and workpiece bore before use to prevent debris from affecting readings. Do not force the gage into an undersized hole, as this can damage the gage surface and affect calibration. Periodic recalibration against a certified master reference is recommended to maintain measurement integrity.
