Spi 19-610-5 Class Zz Minus Plug Pin Gage 0.6100 in

Product Description

The SPI 19-610-5 is a Class ZZ minus plug pin gage designed to verify hole diameters with high dimensional accuracy. It measures a nominal diameter of 0.6100 inches and holds a tolerance of 0.0002 inches, placing it within Class ZZ specifications for go/no-go inspection work. Constructed from steel, this gage is built to withstand repeated use in production and quality-control environments. Machinists, toolmakers, and quality technicians use plug gages like this one to confirm that bored, drilled, or reamed holes fall within allowable limits before parts move to the next stage of assembly.

This gage is suited for use in machine shops, manufacturing facilities, and inspection departments where hole-diameter verification is part of a standard quality process. The minus designation means the gage is ground to the lower end of the tolerance band, making it appropriate for go-gage applications where confirming minimum acceptable hole size is the objective. It is well matched to light-duty inspection tasks involving ferrous and non-ferrous workpieces.

Key Features

• Nominal diameter of 0.6100 inches for precise hole verification
• Class ZZ tolerance of 0.0002 inches for go/no-go inspection accuracy
• Minus designation ground to the lower tolerance boundary
• Steel construction for durability in production environments
• Single-piece packaging with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-use plug gage for standard Class ZZ go/no-go inspection setups requiring a 0.6100-inch nominal diameter measurement.

Installation Notes

Plug pin gages are handled by quality technicians and machinists and require no installation in the traditional sense. Store the gage in a protected case away from moisture and other metal parts to prevent corrosion and surface damage. Clean the gage and the workpiece hole before use to remove chips, oil, or debris that could affect the measurement reading. Do not force the gage into a hole; firm hand pressure only is appropriate to avoid wear or damage to the gage surface.
