Spi 19-926-5 Class Zz Minus Plug Pin Gage 0.926 in

Product Description

The SPI 19-926-5 is a Class ZZ minus plug pin gage designed to verify bore and hole dimensions with high precision. It measures 0.926 inches in diameter and is manufactured from steel for durability under repeated use in shop-floor and inspection environments. The minus tolerance configuration means the gage is manufactured to the low side of the nominal diameter, with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection routines where tight dimensional control is required. Machinists, quality control technicians, and tool and die professionals use plug pin gages as a fast, reliable method to confirm that drilled, reamed, or bored holes meet print specifications.

This gage is suited for use in precision measurement and quality inspection applications across manufacturing, machining, and fabrication settings. It is appropriate for both production-line inspection and tool room use. The 0.926-inch nominal diameter targets a specific hole size commonly encountered in mechanical component manufacturing. Its compact form allows use in a wide range of part geometries where bore access is limited.

Key Features

• Class ZZ tolerance class, manufactured to minus (low) side of nominal for go-gage applications
• 0.926-inch nominal measurement diameter
• Tolerance of 0.0002 inches for high-accuracy dimensional verification
• Steel construction for wear resistance and long service life
• Compact single-pin form factor for use in tight bore access situations

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in bore and hole inspection applications requiring a 0.926-inch nominal diameter check.

Installation Notes

Plug pin gages are used by quality control and machining professionals and require no permanent installation. Before use, ensure the gage and workpiece surfaces are clean and free of debris to prevent false readings or gage wear. Handle with care to avoid dropping, which can alter the gage geometry and invalidate measurements. Calibration and storage practices should follow applicable metrology standards to maintain accuracy over time.
