Spi 29-960-2 Class Zz Plus Plug Gage 0.96 in Dia

Product Description

The SPI 29-960-2 is a Class ZZ Plus plug gage designed for precision bore and hole measurement in industrial and machining environments. Built to a 0.96-inch nominal diameter with a tolerance of 0.0002 inches, this gage provides reliable go/no-go verification for quality control and inspection workflows. The steel construction offers durability in shop-floor conditions. Machinists, tool and die makers, and quality technicians use plug gages like this one to confirm that drilled, reamed, or bored holes fall within acceptable dimensional limits before parts move to the next stage of production.

This plug gage is suited for use in precision manufacturing, machining shops, and inspection departments where hole diameter conformance must be verified quickly and accurately. It fits into standard go/no-go inspection procedures for workpieces requiring a 0.96-inch bore diameter held to tight tolerances. The compact form factor and lightweight design at 0.2 pounds make it easy to handle during repeated inspection cycles on the shop floor or in a dedicated metrology area.

Key Features

• Class ZZ Plus accuracy with 0.0002-inch tolerance for reliable dimensional verification
• 0.96-inch nominal diameter for precise bore and hole inspection
• Steel construction for durability in production and inspection environments
• Lightweight at 0.2 pounds for easy single-handed use during inspection
• Single-piece packaging ready for immediate deployment in quality control workflows

Compatibility

Designed as an OEM-style precision measurement tool for use in any go/no-go inspection setup requiring a 0.96-inch diameter plug gage conforming to Class ZZ Plus tolerances.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and metrology personnel — no power tools or trade licensing required. Clean the gage and the bore thoroughly before use to prevent debris from affecting readings. Store the gage in its protective case when not in use to prevent wear to the precision-ground surfaces. Do not force the gage into an undersize bore, as this can damage both the gage and the workpiece.
