Spi 29-107-0 Class Zz Plus Plug Gage 0.107 in

Product Description

The SPI 29-107-0 is a Class ZZ Plus plug gage designed to verify hole diameter tolerance in precision machining and quality inspection applications. This fixed-limit gage checks a nominal diameter of 0.107 inches with a tolerance of 0.0002 inches, making it suitable for tight-tolerance inspection work where dimensional accuracy is critical. Constructed from steel, it provides the durability and wear resistance required for repeated use in production or tool-room environments. Machinists, quality technicians, and precision tooling professionals rely on this type of gage for fast, reliable go/no-go style dimensional verification.

This plug gage is used in shop-floor and inspection-room settings where small-diameter hole gauging is required. It is appropriate for residential tooling operations, commercial machining shops, and quality control departments performing incoming or in-process inspection. The 0.107-inch diameter range targets small-bore applications commonly encountered in precision component manufacturing, instrument assembly, and similar trades.

Key Features

• Class ZZ Plus tolerance class for precision hole-diameter verification
• Nominal measurement diameter of 0.107 inches
• Tight tolerance of 0.0002 inches for accurate go/no-go inspection
• Steel construction for durability and resistance to wear
• Compact and lightweight at 0.2 pounds for easy bench or field use

Compatibility

Designed as an OEM-style fixed-limit plug gage for small-bore diameter inspection in standard precision machining and quality control applications requiring a 0.107-inch nominal diameter.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians — no power tools or electrical shutoff is required. Clean the gage and the bore being measured before use to prevent debris from affecting readings. Store the gage in its protective case when not in use to prevent damage to the precision-ground surfaces. Follow your facility calibration and metrology procedures to ensure measurement traceability.
