Spi 19-605-5 Class Zz Minus Plug Pin Gage 0.605 in

Product Description

The SPI 19-605-5 is a Class ZZ minus plug pin gage ground to a 0.605-inch nominal diameter with a minus tolerance of 0.0002 inches. It is used to verify bore and hole dimensions in precision machining and quality-control applications. The minus designation means the gage is manufactured to the lower boundary of the tolerance band, making it suitable for go/no-go inspection routines where the gage must pass freely through a conforming hole. Constructed from steel, this pin gage delivers the hardness and dimensional stability required for repetitive inspection work on the shop floor or in a metrology lab. Machinists, quality technicians, and tool-and-die professionals are the primary users.

This pin gage is suited for dimensional inspection of drilled, reamed, or bored holes in metal, plastic, and composite workpieces. It is commonly used in manufacturing environments where hole-location tolerances are held to close limits and documentation of conformance is required. The 0.605-inch diameter places this gage in the range commonly encountered in medium-bore hydraulic, pneumatic, and mechanical component inspection.

Key Features

• Class ZZ accuracy grade with minus tolerance orientation for go-side inspection
• 0.0002-inch tolerance for close-tolerance bore verification
• 0.605-inch nominal diameter, suitable for medium-bore applications
• Steel construction for hardness and dimensional stability under repeated use
• Lightweight at 0.2 pounds, easy to handle during high-volume inspection routines

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in go/no-go inspection sets and individual bore-verification applications where a 0.605-inch diameter pin is specified.

Installation Notes

Pin gages require no installation but should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips and debris that could cause a false rejection or damage the gage surface. Store pin gages in a protective case away from other tooling to prevent nicking or scoring the precision-ground diameter.
