Spi 19-585-9 Class Zz Minus Plug Pin Gage 0.585 in

Product Description

The SPI 19-585-9 is a Class ZZ minus plug pin gage machined to a 0.585-inch nominal diameter with a tolerance of 0.0002 inches. Pin gages in the Class ZZ designation are standard-grade GO/NO-GO inspection tools used to verify hole diameters, slot widths, and feature geometry on machined parts. The 19-585-9 is manufactured from steel, providing the hardness and dimensional stability required for reliable measurement work on the shop floor or in a quality-inspection setting. Machinists, toolmakers, and quality technicians use plug pin gages as a fast, repeatable method to confirm that drilled, reamed, or punched features fall within specified tolerance limits.

This gage is suited for production inspection environments where a single diameter is checked repeatedly across multiple parts. It is appropriate for use in machine shops, fabrication facilities, and manufacturing quality departments. The 0.585-inch size covers a specific hole diameter that is common in general-purpose machined components. Because it is a minus gage, the gage diameter is ground below the nominal dimension by the stated tolerance, which is consistent with standard GO-gage application in tolerance verification workflows.

Key Features

• Class ZZ minus designation for standard-grade hole and feature inspection
• Nominal diameter of 0.585 inches with a 0.0002-inch tolerance
• Steel construction for durability and dimensional stability during repeated use
• Single-piece plug gage format for fast, simple GO or NO-GO checks
• Lightweight at 0.2 pounds for easy handling during production inspection

Compatibility

Designed as a standard replacement or supplemental Class ZZ plug pin gage for inspection setups requiring a 0.585-inch nominal diameter measurement. Verify that the tolerance class and diameter match your inspection plan before use.

Installation Notes

Plug pin gages require no installation but should be handled with care to avoid surface damage that could affect measurement accuracy. Clean the gage and the feature being checked before use to remove chips, oil, or debris. Store the gage in a protective case when not in use and allow it to reach ambient temperature before taking measurements if it has been moved from a temperature-controlled area. Periodic calibration against a traceable standard is recommended to maintain measurement integrity in quality-controlled environments.
