Spi 29-162-5 Class Zz Plus Plug Gage 0.162 in

Product Description

The SPI 29-162-5 is a Class ZZ Plus plug gage designed for precision bore and hole measurement in manufacturing, machining, and inspection environments. It measures a nominal diameter of 0.162 inches with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection routines where tight dimensional control is required. Constructed from steel, this gage provides the durability and wear resistance expected in production and quality-control settings. Machinists, tool-and-die makers, and quality technicians use plug gages like this one to verify that drilled, reamed, or bored holes meet print specifications before parts move to the next stage of production.

The SPI 29-162-5 is used in machine shops, fabrication facilities, and inspection labs where small-diameter hole verification is part of the standard quality workflow. It is well-suited for checking holes in metal components where the nominal diameter falls at 0.162 inches. Class ZZ Plus designation indicates this gage meets the tolerance and accuracy standards associated with working gages used in production inspection rather than master or reference gage applications.

Key Features

• Nominal measurement diameter of 0.162 inches for small-bore inspection
• Tolerance of 0.0002 inches meets Class ZZ Plus accuracy standards
• Steel construction provides wear resistance for repeated production use
• Compact single-piece design suitable for go/no-go inspection setups
• UNSPSC Code 41111600 for straightforward procurement classification

Compatibility

Designed as a working-class plug gage for production inspection of holes with a nominal diameter of 0.162 inches. Compatible with standard gage handle holders sized for this diameter range.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and inspection personnel. Store the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a hole; apply light, consistent hand pressure to avoid damaging the gage or the workpiece. Calibrate and inspect gages periodically per your facility's measurement system analysis and quality control procedures.
