Spi 29-763-0 Class Zz Plus Plug Gage 0.763 in

Product Description

The SPI 29-763-0 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a precise 0.763-inch nominal size. It holds a tolerance of 0.0002 inches, making it suited for inspection and quality-control work where tight dimensional verification is required. Constructed from steel, this plug gage provides the durability and wear resistance expected in production and inspection environments. Machinists, toolmakers, and quality technicians use plug gages like this to confirm that drilled, reamed, or bored features fall within specified limits before parts advance through the manufacturing process.

The SPI 29-763-0 is intended for use in dimensional inspection of cylindrical holes and bores measuring 0.763 inches in diameter. Class ZZ Plus gages are commonly applied in go/no-go inspection routines in job shops, production machining facilities, and metrology labs. This gage is appropriate for both incoming material inspection and in-process quality checks wherever bore diameter conformance is critical.

Key Features

• 0.763-inch nominal diameter for direct bore and hole verification
• Class ZZ Plus tolerance of 0.0002 inches for precision dimensional inspection
• Steel construction for wear resistance and long service life
• Single-piece package quantity ready for immediate deployment
• UNSPSC Code 41111600 — classified under precision measuring instruments

Compatibility

Designed as an OEM-style replacement or direct-use plug gage for any application requiring go/no-go or dimensional inspection of 0.763-inch diameter cylindrical features.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and inspection personnel — no power tools or utilities need to be shut down for their use. Store the gage in a protective case away from abrasive surfaces and temperature extremes to preserve calibration integrity. Clean the gage and the bore being measured before use to prevent false readings from debris or cutting fluid. Follow your facility's calibration schedule and handling protocols as recommended by applicable metrology standards.
