Spi 19-713-7 Class Zz Minus Plug Pin Gage 0.713 in

Product Description

The SPI 19-713-7 is a Class ZZ minus plug pin gage with a nominal diameter of 0.713 inches, manufactured from steel. Pin gages of this class are used to verify hole diameters, check bore tolerances, and confirm dimensional compliance during inspection and quality control operations. The minus tolerance designation means the gage is ground to the lower boundary of the tolerance band, which is standard practice for go-no-go and attribute gauging applications. With a tolerance of 0.000200 inches, this gage is suited for moderate-precision inspection tasks in machine shops, production lines, and metrology departments.

Class ZZ plug gages are the most common class for general-purpose inspection work in manufacturing and fabrication environments. This 0.713-inch diameter gage is typically used by machinists, quality control inspectors, and tool-and-die professionals to verify drilled, reamed, or bored holes meet print specifications. It fits standard gage handle sets for convenient single-hand use during high-volume or bench inspection work.

Key Features

• Class ZZ minus designation for general-purpose attribute gauging at the lower tolerance boundary
• Nominal diameter of 0.713 inches for direct hole-size verification
• Tolerance of 0.000200 inches for consistent, repeatable measurement results
• Steel construction for durability and resistance to wear under regular inspection use
• Compatible with standard plug gage handles for ergonomic bench or floor use

Compatibility

Designed for use with standard plug gage handle sets sized for the 0.713-inch diameter range. Fits typical two-end gage handle configurations common in general metrology applications.

Installation Notes

Plug pin gages are handled and used by machinists, quality technicians, and inspection personnel rather than installed in a system. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion. Do not force the gage through an undersized hole, as this can damage both the gage and the workpiece. Store in a gage case or protective sleeve away from abrasive surfaces to maintain calibration integrity.
