Spi 11-367-0 Bore Gage Block Kit Calibration Master

Product Description

The SPI 11-367-0 is a bore gage block kit calibration master designed to set and verify inside bore gages across a measurement range of 0.05 to 4 inches. Accurate to 0.00005 inches, this kit gives metrology technicians and quality control professionals a reliable reference standard for calibrating bore gages in shop or lab environments. The kit is constructed of steel for dimensional stability and resistance to wear. A fitted case is included to protect the blocks during storage and transport. This master is suited for applications where traceable, repeatable gage calibration is required on the shop floor or in a quality lab.

The 11-367-0 is used in manufacturing, machining, and quality assurance environments where bore gage accuracy must be verified or reset. Typical applications include setting plug gages, dial bore gages, and air gages prior to inspection runs. The steel construction maintains dimensional integrity across standard shop temperature ranges, making it a practical choice for both bench-top calibration stations and mobile gage-setting carts. The included case keeps the blocks organized and protects precision ground surfaces between uses.

Key Features

• Measurement range: 0.05 to 4 inches for broad bore gage coverage
• Accuracy: 0.00005 inches for precise calibration reference
• Steel construction for dimensional stability and long service life
• Includes fitted carrying and storage case
• Kit format with multiple blocks covers a wide range of bore diameters in a single set

Compatibility

Designed as a calibration master for inside bore gages including dial bore gages, plug gages, and similar inside measuring instruments requiring a precision reference standard in the 0.05 to 4 inch range.

Installation Notes

Calibration masters should be handled only by qualified metrology or quality control personnel familiar with gage block handling procedures. Clean all contact surfaces before use to prevent contamination from affecting accuracy. Store blocks in the provided case when not in use and allow adequate thermal soak time when moving blocks from a temperature-controlled environment to the shop floor. Follow your facility calibration procedures and applicable ANSI or ISO standards for gage calibration intervals and documentation.
