Spi 19-100-7 Class Zz Minus Plug Pin Gage 0.1 in

Product Description

The SPI 19-100-7 is a Class ZZ minus plug pin gage used to verify bore and hole diameters in precision machining and inspection applications. Built from steel, this pin gage checks whether a feature is within tolerance by confirming a minimum acceptable diameter. The nominal diameter is 0.1 inches with a minus tolerance of 0.000200 inches, making it suitable for go/no-go inspection workflows where tight dimensional control is required. Machinists, quality control technicians, and toolroom professionals use this type of gage as part of standard inspection routines on production and job-shop floors.

Class ZZ plug gages are the standard grade for general-purpose inspection of holes, bores, and drilled features in steel, aluminum, and similar workpiece materials. This pin gage is appropriate for use in manufacturing facilities, machine shops, and inspection departments where dimensional verification of small-diameter features is performed routinely. The 0.1-inch nominal size targets small-bore work including drilled holes, reamed bores, and machined features at that diameter range.

Key Features

• Class ZZ tolerance class for general-purpose dimensional inspection
• Minus configuration confirms minimum acceptable hole diameter
• 0.000200-inch tolerance for precise go/no-go verification
• Steel construction for durability in production and toolroom environments
• 0.1-inch nominal diameter targets small-bore machined features

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general-purpose hole and bore inspection applications requiring a 0.1-inch nominal diameter check.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists and do not require installation in the traditional sense. Store the gage in its protective case when not in use to prevent wear and corrosion on the gauging surface. Clean the gage and the workpiece bore before use to prevent debris from affecting measurement accuracy. Handle with care to avoid dropping, as impact damage can alter the gage diameter and compromise inspection validity.
