Spi 19-924-0 Class Zz Minus Plug Pin Gage 0.924 in

Product Description

The SPI 19-924-0 is a Class ZZ minus plug pin gage designed to verify bore and hole diameters with precision. This gage measures a nominal diameter of 0.924 inches and carries a minus tolerance of 0.0002 inches, ensuring accurate go/no-go inspection on the shop floor or in a quality control setting. Constructed from steel for dimensional stability and wear resistance, it is a standard tool for machinists, toolmakers, and quality technicians performing dimensional inspection of machined parts.

Class ZZ plug gages are commonly used in production and inspection environments where moderate-tolerance hole verification is required. This gage is suited for checking drilled, reamed, or bored holes in manufacturing and fabrication applications. It fits standard pin gage handle sets and is appropriate for use in both light production and incoming inspection workflows where consistent, repeatable diameter verification is needed.

Key Features

• 0.924-inch nominal measurement diameter for precise bore inspection
• Class ZZ minus tolerance of 0.0002 inches for reliable go/no-go gauging
• Steel construction provides durability and dimensional stability under repeated use
• Compatible with standard plug gage handles for flexible application
• Single-piece package quantity suitable for individual replacement or kit supplementing

Compatibility

Designed as an OEM-style replacement or supplemental gage member for standard plug gage handle sets accepting members in the 0.924-inch diameter range.

Installation Notes

Plug pin gages are installed and used by machinists and quality control technicians. Before use, clean the gage member and the bore being inspected to remove debris, oil, or chips that could affect readings. Handle gage members by the knurled shank or with appropriate gage handling tools to avoid introducing measurement error through thermal expansion from hand contact. Store gage members in a protective case when not in use to prevent nicks and corrosion that degrade accuracy.
