Spi 29-119-5 Class Zz Plus Plug Gage 0.119 in

Product Description

The SPI 29-119-5 is a Class ZZ Plus plug gage used to verify bore diameters with a nominal measurement of 0.119 inches and a tolerance of 0.0002 inches. Plug gages of this class are GO/NO-GO style inspection tools that allow machinists, quality control technicians, and tool room personnel to confirm that drilled, reamed, or bored holes meet specified dimensional requirements. The steel construction provides durability through repeated use in production and inspection environments. This gage is suited for applications where close-tolerance verification is required on small-diameter features.

This gage is used in machine shops, manufacturing facilities, and quality inspection departments for dimensional verification of small bores and holes. It is appropriate for incoming inspection, in-process checks, and final acceptance testing. The 0.119-inch diameter size is commonly encountered in precision machined parts, tooling components, and small-bore fluid fittings where tight dimensional control is critical.

Key Features

• Class ZZ Plus tolerance rating for small-diameter bore inspection
• 0.119-inch nominal measurement diameter
• 0.0002-inch tolerance for close-tolerance verification
• Steel construction for durability and wear resistance in production use
• Single-piece package quantity suitable for individual workstation use

Compatibility

Designed as a standard Class ZZ Plus plug gage for verifying 0.119-inch nominal bore diameters in precision machined components and assemblies.

Installation Notes

Plug gages should be handled by metrology or quality control personnel trained in gage use and care. Store the gage in a protective case away from chips, coolant, and abrasive surfaces to prevent wear on the measuring surface. Clean the gage and the bore before inspection to ensure accurate readings. Periodic recalibration against traceable standards is recommended to maintain measurement integrity.
