Spi 19-013-2 Class Zz Minus Plug Pin Gage 0.013 in

Product Description

The SPI 19-013-2 is a Class ZZ minus plug pin gage used to verify hole diameters and bore tolerances in precision machining and inspection work. With a nominal diameter of 0.013 inches and a tolerance of 0.0002 inches, this gage provides a go/no-go reference point for quality control checks on small-diameter features. Constructed from steel for dimensional stability, it is sized for use in tight-tolerance applications where hole size verification is critical. Machinists, tool-and-die makers, and quality inspectors use pin gages like this one as part of standard shop-floor and inspection-room measurement routines.

This pin gage is suited for inspecting small precision bores in machined components across manufacturing environments. The 0.013-inch diameter makes it appropriate for verifying very fine holes such as those found in instrument components, nozzles, and precision-machined parts. Class ZZ designates a commercial-grade tolerance class, making this gage practical for general inspection use rather than master or reference applications. It ships individually and is available in single-unit quantities.

Key Features

• 0.013-inch nominal diameter for very small bore inspection
• Class ZZ minus designation provides go/no-go reference for commercial-grade inspection
• 0.0002-inch tolerance for repeatable, accurate measurement results
• Steel construction for dimensional stability and wear resistance
• Single-piece packaging suitable for individual replacement or kit supplementing

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general precision inspection and quality control applications requiring 0.013-inch diameter hole verification.

Installation Notes

Pin gages are handled and used by machinists, quality technicians, and metrologists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore — light hand pressure only is appropriate to avoid bending or damaging a pin of this diameter. Store separately from other tooling to prevent contact damage to the gage surface.
