Spi 19-364-9 Class Zz Minus Plug Pin Gage 0.364 in

Product Description

The SPI 19-364-9 is a Class ZZ minus plug pin gage machined from steel and used to verify bore and hole dimensions in precision inspection work. Sized at 0.364 inches in diameter with a minus tolerance of 0.000200 inches, this gage confirms that a feature meets its minimum acceptable size. Class ZZ is the standard tolerance grade for general-purpose inspection gages used in production and quality-control environments. Machinists, toolmakers, and quality technicians reach for pin gages when checking drilled, reamed, or bored holes against a known dimensional standard.

This gage is suited for use in machine shops, manufacturing facilities, and metrology labs where hole diameter verification is part of a standard inspection routine. It works as a go or no-go reference depending on the inspection protocol in place. The 0.364-inch diameter targets holes in that specific size range, making it a direct fit for applications where that nominal dimension appears on a drawing or process spec.

Key Features

• Class ZZ tolerance grade for general-purpose production inspection
• Minus tolerance configuration at 0.000200 inches for minimum-limit verification
• 0.364-inch nominal diameter for precise hole-size confirmation
• Steel construction for durability and dimensional stability during repeated use
• Compact, lightweight design at 0.2 pounds for easy single-hand handling

Compatibility

Designed as a standard plug pin gage for use in any inspection process requiring verification of a 0.364-inch nominal bore or hole diameter in accordance with Class ZZ gage tolerance standards.

Installation Notes

Pin gages require no installation but should be handled by quality technicians or machinists familiar with proper gage use and care. Clean the gage and the part bore before use to prevent contamination from affecting the measurement result. Store the gage in a protective case when not in use to prevent surface damage that could affect calibration accuracy. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
