Spi 29-713-5 Class Zz Plus Plug Gage 0.713 in

Product Description

The SPI 29-713-5 is a Class ZZ Plus plug gage designed for precision bore and hole inspection. It measures an inside diameter of 0.7130 inches with a tolerance of 0.0002 inches, making it suitable for quality control and go/no-go verification tasks in manufacturing and machining environments. The steel construction provides durability and dimensional stability under repeated use. Dimensional inspectors, machinists, and quality technicians use this gage to verify hole size compliance to print specifications on production and inspection floors.

This plug gage is intended for use in inspection and metrology applications where tight tolerances must be confirmed before parts move to the next production stage. It is well suited for light manufacturing, tool rooms, machine shops, and quality assurance departments working with holes in the 0.713-inch nominal range. The Class ZZ Plus designation indicates a tolerance grade appropriate for functional inspection of production parts rather than master gage or setting gage applications.

Key Features

• 0.7130-inch measurement diameter for precise bore inspection
• 0.0002-inch tolerance consistent with Class ZZ Plus gage standards
• Steel construction for dimensional stability and wear resistance
• Compact and lightweight at 0.2 pounds for easy single-hand use
• Single-piece package quantity for individual or low-volume procurement

Compatibility

Designed as an OEM-style plug gage for go/no-go inspection of bored or drilled holes with a 0.713-inch nominal diameter in general machining and quality control applications.

Installation Notes

Plug gages should be handled by trained dimensional inspection personnel or machinists familiar with gage use and care. Clean the gage and bore contact surfaces before use to prevent measurement error caused by debris or contamination. Do not force the gage into a hole; excessive force can damage the gage land or distort the workpiece bore. Store the gage in a protected case away from heat sources and corrosive environments to preserve calibration integrity.
