Spi 29-701-0 Class Zz Plus Plug Gage 0.701 in Dia

Product Description

The SPI 29-701-0 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal measurement of 0.701 inches. Built from steel, this go/no-go style fixed-limit gage delivers a tolerance of 0.0002 inches, making it suitable for inspection work where tight dimensional verification is required. Machinists, toolroom technicians, and quality control inspectors use plug gages like this one to confirm that drilled, reamed, or bored holes fall within specified tolerance ranges before parts advance to the next stage of production or assembly.

This plug gage is appropriate for use in machine shops, production environments, and toolroom inspection stations. It is used wherever a 0.701-inch nominal diameter hole must be verified against a print tolerance. Class ZZ Plus designation indicates a commercial-grade gage suitable for production inspection of general-tolerance work rather than master or reference-grade calibration tasks.

Key Features

• 0.701-inch nominal diameter for direct hole verification
• Class ZZ Plus tolerance class suited to production inspection
• 0.0002-inch tolerance for precise dimensional confirmation
• Steel construction for durability in shop environments
• Fixed-limit design for fast go/no-go inspection workflow

Compatibility

Designed as an OEM-style fixed-limit plug gage for verifying 0.701-inch nominal diameter holes in standard production inspection applications.

Installation Notes

Plug gages are handled and stored by quality control technicians and toolroom personnel rather than installed in a system. Clean the gage and the bore before use to prevent false readings caused by chips or debris. Store in a protective case away from temperature extremes to maintain dimensional stability. Handle with care to avoid drops or impacts that could alter the gage diameter.
