Spi 19-200-5 Class Zz Minus Plug Pin Gage 0.2 in

Product Description

The SPI 19-200-5 is a Class ZZ minus plug pin gage used to verify bore and hole dimensions in precision inspection and quality control applications. Manufactured from steel, this pin gage checks whether a drilled, reamed, or machined hole meets the minimum acceptable size. The 0.2-inch nominal diameter with a minus tolerance of 0.0002 inches ensures that any hole the gage passes through is confirmed to be at or above the low limit of the specified diameter. Machinists, tool-and-die makers, and quality technicians rely on Class ZZ gages for production-floor inspection work.

This pin gage is suited for use in manufacturing environments where go/no-go hole verification is required. It is appropriate for inspection of drilled, punched, or bored holes in metal, plastic, and composite components. The compact form factor allows use in confined inspection setups and fits standard pin gage handle sets for ease of handling during repetitive inspection cycles.

Key Features

• Class ZZ tolerance class, suitable for production-floor inspection and less critical measuring applications
• Minus designation indicates the gage is ground to the low side of the nominal diameter for go-gage function
• 0.0002-inch (0.0002 mm) tolerance for reliable dimensional verification
• Steel construction provides durability and resistance to wear under regular shop use
• 0.2-inch nominal diameter covers common small bore inspection requirements
• Compatible with standard pin gage handle sets for convenient measurement workflow

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in go/no-go hole inspection setups; fits standard pin gage handles sized for the 0.2-inch diameter range.

Installation Notes

Pin gages are handled by quality technicians and machinists and require no permanent installation. Store the gage in its protective case when not in use to prevent burring or surface contamination that could affect accuracy. Clean the gage and the part bore with a lint-free cloth before measurement to remove chips, oil, or debris. Never force a pin gage through a hole; doing so can damage the gage surface and invalidate the measurement.
