Spi 29-695-4 Class Zz Plus Plug Gage 0.695 Inch

Product Description

The SPI 29-695-4 is a Class ZZ Plus plug gage designed for go/no-go inspection of hole diameters in production and quality-control environments. It measures a nominal diameter of 0.695 inches with a tolerance of 0.0002 inches, providing the close repeatability required for precision hole verification. Constructed from steel, the gage is built to withstand repeated use in shop-floor conditions while maintaining dimensional integrity. Machinists, quality technicians, and tool-room professionals use this type of gage to confirm that drilled, reamed, or bored holes meet specified tolerances before parts advance to the next stage of production.

Class ZZ Plus plug gages are suited for general-purpose inspection tasks where moderate tolerance requirements apply. This gage is appropriate for use in manufacturing, fabrication, and inspection settings where verifying a 0.695-inch hole diameter is part of a standard quality process. It is typically used in conjunction with a gage handle and is appropriate for both low-volume inspection and repetitive production-line checks.

Key Features

• Nominal measurement diameter of 0.695 inches for precise hole inspection
• Class ZZ Plus tolerance rating of 0.0002 inches for reliable go/no-go gauging
• Steel construction for durability and dimensional stability under repeated use
• Compact and lightweight at 0.2 pounds for easy handling
• Single-piece package quantity for individual replacement or addition to an existing gage set

Compatibility

Designed as an OEM-style replacement or supplemental gage for standard plug gage handle systems accepting Class ZZ Plus gage members at the 0.695-inch diameter range.

Installation Notes

Plug gages are installed and used by quality technicians and machinists; no power source or utility shutoff is required. Thread the gage member securely into a compatible gage handle before use. Keep the gage clean and lightly oiled when stored to prevent corrosion and maintain calibration accuracy. Do not force the gage into an undersized hole, as this can damage the gage surface and invalidate measurements.
