Spi 19-586-7 Class Zz Minus Plug Pin Gage 0.586 in

Product Description

The SPI 19-586-7 is a Class ZZ minus plug pin gage used to verify hole diameters and bore tolerances in precision machining and inspection applications. Ground to a nominal diameter of 0.586 inches with a minus tolerance of 0.0002 inches, this gage provides a reliable no-go or go reference for quality control checks. The steel construction resists wear during repeated use in shop-floor and inspection-room environments. Machinists, toolroom technicians, and quality control inspectors use plug gages like this one to confirm that drilled, reamed, or bored features fall within specified dimensional limits.

Class ZZ plug gages are the standard working-grade gage for general inspection use in manufacturing and fabrication settings. This 0.586-inch diameter gage is suited for checking through-holes and blind bores in metal, plastic, or composite workpieces where dimensional conformance is required. It is a single-end minus gage, meaning the ground diameter is undersized relative to nominal by the stated tolerance, making it appropriate for go-gage applications where the gage must pass through an acceptable hole.

Key Features

• Nominal diameter of 0.586 inches ground to Class ZZ minus tolerance standards
• Tolerance of 0.0002 inches for precise dimensional verification
• Steel construction for durability and dimensional stability during repeated use
• Single-end minus configuration for go-gage inspection setups
• Compact and lightweight at 0.2 pounds for easy bench and hand use

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use with any workpiece or fixture requiring verification of a 0.586-inch nominal diameter bore or hole feature.

Installation Notes

Plug pin gages do not require installation in a traditional sense but should be handled and stored carefully to prevent damage to the precision ground surface. Always clean the gage and the workpiece bore before use to ensure accurate measurement results. Do not force the gage into an undersized hole, as this can cause damage to both the gage and the part. Calibration and gage-block traceability practices should follow applicable metrology standards in your facility.
