Spi 19-536-2 Class Zz Minus Plug Pin Gage 0.536 in

Product Description

The SPI 19-536-2 is a Class ZZ minus plug pin gage used to check bore diameters and hole tolerances in precision machining and inspection work. It measures a nominal diameter of 0.536 inches with a minus tolerance of 0.0002 inches, confirming that a hole or bore does not exceed its specified lower limit. Made from steel, this gage is handled by machinists, quality control technicians, and tool room personnel who need reliable go/no-go verification on the shop floor or in the inspection lab.

Class ZZ plug gages are the standard choice for general-purpose inspection of production parts where consistent hole sizing is critical. This 0.536-inch gage fits into quality assurance workflows for manufactured components across industries including industrial equipment, fluid system assemblies, and precision fabrication. It is used wherever repeatable dimensional verification of drilled, reamed, or bored holes is required.

Key Features

• Nominal diameter of 0.536 inches for precise bore inspection
• Class ZZ minus tolerance of 0.0002 inches for general-purpose go/no-go gauging
• Steel construction for durability and dimensional stability under repeated use
• Compact and lightweight at 0.2 pounds for easy handling during inspection
• Single-piece packaging suitable for individual replacement or toolroom stocking

Compatibility

Designed as an OEM-style replacement or direct addition to Class ZZ plug gage sets used for general-purpose bore and hole inspection in standard inch-measurement applications.

Installation Notes

Plug pin gages are handled by machinists or quality inspectors and require no mechanical installation. Before use, ensure the gage and the workpiece bore are clean and free of debris or cutting fluid that could affect measurement accuracy. Do not force the gage into an undersized bore, as this can damage the gage or the part. Store in a protective case away from temperature extremes to maintain dimensional integrity.
