Spi 19-060-3 Class Zz Minus Plug Pin Gage 0.0600 in

Product Description

The SPI 19-060-3 is a Class ZZ minus plug pin gage used to verify bore and hole diameters to a high degree of precision. It measures a nominal diameter of 0.0600 inches with a tolerance of 0.000200 inches, making it suitable for quality control and inspection tasks in machine shops, manufacturing facilities, and toolrooms. The steel construction provides the durability and dimensional stability required for repeated use in production environments. Metrology technicians and quality inspectors rely on this type of gage to confirm that drilled, reamed, or bored holes meet drawing specifications before parts move forward in the assembly process.

This plug pin gage is used in precision measurement applications where small-diameter hole inspection is required. Class ZZ gages are a common choice for general inspection and shop-floor go/no-go verification of holes in the 0.0600-inch range. The minus designation indicates the gage is manufactured to the lower tolerance limit, which is standard practice for plug gages used in this class. Typical users include quality control inspectors and machinists working in light manufacturing, aerospace component inspection, and precision fabrication shops.

Key Features

• Nominal measurement diameter of 0.0600 inches for small-bore inspection
• Class ZZ tolerance of 0.000200 inches for general-purpose precision measurement
• Minus designation conforms to standard plug gage manufacturing convention
• Steel construction for dimensional stability and wear resistance
• Single-piece package quantity suitable for individual workstation use

Compatibility

Designed as a general-purpose plug pin gage for inspecting holes with a nominal diameter of 0.0600 inches in standard shop and inspection applications.

Installation Notes

Plug pin gages are handled and used by quality control inspectors and metrology personnel rather than installed in a mechanical system. Before use, clean the gage and the hole being inspected to remove chips, oil, and debris that could affect the measurement reading. Do not force the gage into a hole, as this can damage both the gage and the workpiece and produce inaccurate results. Store the gage in a protective case away from temperature extremes to preserve dimensional accuracy.
