Spi 29-984-2 Class Zz Plus Plug Gage 0.984 in

Product Description

The SPI 29-984-2 is a Class ZZ Plus plug gage used to verify inside diameter dimensions in precision machining and quality control applications. It measures a nominal diameter of 0.984 inches with a tolerance of 0.0002 inches, making it suitable for go/no-go inspection work where tight dimensional accuracy is required. Constructed from steel, this gage is built to withstand repeated use in shop floor environments. Machinists, quality technicians, and tool room professionals use plug gages like this one to confirm that bored, drilled, or reamed holes fall within specified tolerance limits before parts move to the next stage of production.

This plug gage is designed for use in dimensional inspection of holes requiring a 0.984-inch nominal diameter check. It is appropriate for use in manufacturing, metalworking, and precision machining shops handling both prototype and production runs. The Class ZZ Plus designation indicates a commercial-grade tolerance classification, making it a practical choice for general inspection tasks where laboratory-grade accuracy is not required but reliable measurement is essential.

• Class ZZ Plus classification suitable for general commercial inspection use
• Steel construction for durability in production and tool room environments
• Single-piece package quantity, sold individually

Compatibility

Designed as an OEM-style replacement or standard inspection tool for applications requiring inside diameter verification at 0.984 inches nominal diameter in general machining and quality control workflows.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians. Clean the gage and the hole to be 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 ground surfaces. Do not force the gage into an undersized hole, as this can damage the gage or the workpiece.
