Spi 19-436-5 Class Zz Minus Plug Pin Gage 0.436 in

Product Description

The SPI 19-436-5 is a Class ZZ minus plug pin gage designed to verify bore and hole dimensions with precision in production and inspection environments. Built to a nominal diameter of 0.436 inches with a minus tolerance of 0.0002 inches, this gage provides reliable go/no-go measurement confirmation for quality control workflows. Constructed from steel for durability under repeated use, it is a standard tool for machinists, quality technicians, and precision measurement professionals working to tight dimensional tolerances on machined components.

Class ZZ plug gages are suited for general-purpose inspection work where high-volume, repetitive checking of hole sizes is required. This gage is commonly used in machine shops, fabrication facilities, and manufacturing quality departments to verify that drilled, reamed, or bored holes fall within specified dimensional limits. The minus designation indicates the gage is ground to the lower boundary of the tolerance band, making it appropriate for confirming minimum acceptable hole size.

Key Features

• Nominal diameter of 0.436 inches for direct hole verification at that dimension
• Class ZZ minus tolerance of 0.0002 inches for general-purpose inspection accuracy
• Steel construction provides wear resistance and dimensional stability during repeated use
• Compact form factor suited for bench inspection and in-process checking
• Single-piece design with no adjustable components, reducing calibration complexity

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in general-purpose dimensional inspection of holes and bores measuring 0.436 inches in diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Store the gage in a protective case when not in use to prevent surface damage that could affect dimensional accuracy. Clean the gage and the workpiece bore before use to remove chips, coolant, or debris that could produce false readings. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise measurement integrity.
