Spi 29-947-9 Class Zz Plus Plug Gage 0.947 in Dia

Product Description

The SPI 29-947-9 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a precise 0.947-inch nominal size. It provides a go/no-go style reference for quality control and inspection tasks in machine shops, manufacturing facilities, and maintenance environments. Built from steel, the gage delivers consistent dimensional checks with a tolerance of 0.0002 inches, making it appropriate for general-purpose inspection where close but not ultra-precision tolerances are required. Machinists, tooling inspectors, and quality control technicians are the primary users of this gage type.

This plug gage is suited for inspecting drilled, reamed, or bored holes in metal or composite workpieces where a 0.947-inch diameter is the specified nominal. It applies to production floor inspection, incoming material verification, and general metrology tasks. The Class ZZ Plus designation indicates it meets standard commercial-grade accuracy requirements for plug gages, making it a practical choice for routine dimensional verification on the shop floor or in the field.

Compatibility

Designed as an OEM-style inspection gage for any application requiring dimensional verification of 0.947-inch nominal diameter bores or holes in metal or composite workpieces.

Installation Notes

Plug gages are inspection tools and do not require mechanical installation. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in a protective case away from abrasive materials when not in use. Calibrate or verify the gage against a certified master reference at regular intervals per your quality management system requirements.
