Spi 19-582-6 Class Zz Minus Plug Pin Gage 0.582 in

Product Description

The SPI 19-582-6 is a Class ZZ minus plug pin gage used to verify bore and hole diameters in precision machining and inspection applications. Manufactured from steel, this pin gage measures 0.582 inches in nominal diameter and holds a minus tolerance of 0.0002 inches, making it suitable for go/no-go gauging workflows where dimensional accuracy is critical. Machinists, quality control technicians, and tool-and-die professionals use pin gages like this one to confirm that drilled, reamed, or bored features meet drawing specifications before parts advance to the next production stage.

Class ZZ plug pin gages are typically used in production and general inspection environments where tolerance requirements are less stringent than Class Z or Class X applications. This gage is appropriate for checking hole diameters in metal, plastic, and composite workpieces across both job-shop and manufacturing floor settings. The 0.582-inch size fits common shaft and bore configurations found in mechanical assemblies and fixture work.

Key Features

• Class ZZ minus tolerance rating for production-grade go/no-go inspection
• 0.582-inch nominal diameter for precise hole and bore verification
• Minus tolerance of 0.0002 inches ensures the gage falls within the low side of the tolerance band
• Steel construction for durability and dimensional stability under normal shop conditions
• Compact and lightweight at 0.2 pounds for easy single-hand use

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general production inspection of 0.582-inch nominal diameter bores and holes.

Installation Notes

Pin gages are handled and used by machinists and quality technicians — no power tools or electrical shutoff is required. Clean the gage and the bore being checked before use to prevent contamination from affecting the reading. Store pin gages in their protective case when not in use to prevent surface damage or corrosion that could alter the calibrated diameter. Recalibrate or replace the gage if it shows signs of wear, burring, or surface pitting that may affect accuracy.
