Spi 29-802-6 Class Zz Plus Plug Gage 0.802 in

Product Description

The SPI 29-802-6 is a Class ZZ Plus plug gage used to verify the inside diameter of machined holes and bores. Measuring at a nominal diameter of 0.802 inches with a tolerance of 0.0002 inches, this gage delivers the precision required for quality control inspection in machine shops, manufacturing facilities, and tool rooms. The steel construction provides durability and resistance to wear under repeated use. It is typically handled by machinists, quality inspectors, and tool and die professionals performing go/no-go acceptance checks on production parts.

This plug gage is suited for inspecting drilled, reamed, or bored holes where tight dimensional control is critical. At 0.802 inches nominal diameter, it fits a common range of precision machined components encountered in industrial and manufacturing environments. Its Class ZZ Plus classification indicates it meets the standard tolerancing requirements for working gages used in general inspection applications. The compact size and light weight of 0.2 pounds make it easy to handle during routine inspection tasks on the shop floor or at a quality station.
