Spi 19-592-5 Class Zz Minus Plug Pin Gage 0.592 in

Product Description

The SPI 19-592-5 is a Class ZZ minus plug pin gage designed to verify hole diameters and bore tolerances in precision machining and inspection applications. Manufactured from steel, this gage checks a nominal diameter of 0.592 inches with a tolerance of 0.0002 inches, providing the dimensional accuracy required for go/no-go inspection work. Class ZZ designates a standard commercial-grade tolerance class suitable for general inspection use in job shop and production environments. Machinists, quality control technicians, and toolroom professionals use pin gages like this one to confirm that bored, drilled, or reamed holes fall within specified limits.

This pin gage is appropriate for use in manufacturing, fabrication, and quality inspection settings where hole size verification is part of standard workflow. It is suited for checking 0.592-inch nominal bores in metal, plastic, or composite workpieces. The minus designation indicates the gage is ground to the lower boundary of the tolerance band, following standard plug gage convention for go-gage application. It is typically used as part of a larger pin gage set or as a standalone replacement gage for a specific diameter requirement.

Key Features

• Class ZZ tolerance class for general commercial inspection use
• Minus designation ground to the lower tolerance boundary for go-gage application
• 0.592-inch nominal diameter with 0.0002-inch tolerance
• Steel construction for durability and dimensional stability
• Compact form factor at 0.2 pounds for easy single-hand use

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general hole inspection applications requiring a 0.592-inch nominal bore diameter check.

Installation Notes

Pin gages are handled and used by machinists and quality inspection personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the gage into a bore; insertion should require only light hand pressure. Store separately from other tooling to prevent contact damage to the ground surface.
