Spi 29-362-1 Class Zz Plus Plug Gage 0.362 Inch

Product Description

The SPI 29-362-1 is a Class ZZ Plus plug gage used to verify the diameter of machined holes to a high degree of precision. Designed for go/no-go inspection work, this gage checks whether a bored or drilled hole falls within an acceptable tolerance range. The nominal measurement diameter is 0.362 inches, with a tolerance of 0.0002 inches, making it suitable for applications where tight dimensional control is required. The steel construction provides durability for repeated use in shop-floor and inspection environments. Machinists, toolmakers, and quality control technicians typically work with this type of gage.

Class ZZ Plus plug gages are used in manufacturing and machining environments where hole-diameter verification is part of the inspection process. This gage is appropriate for both production-line inspection and toolroom use. It is suited to residential shop, light industrial, and precision manufacturing settings where compliance with dimensional tolerances must be confirmed before parts proceed to assembly. The 0.362-inch nominal diameter targets a specific hole size common in machined components requiring consistent fit.

Key Features

• 0.362-inch nominal measurement diameter for precise hole inspection
• 0.0002-inch tolerance for tight dimensional verification
• Class ZZ Plus classification meets standard go/no-go gage accuracy requirements
• Steel construction for durability in shop and inspection environments
• Compact form factor suited to handheld inspection use

Compatibility

Designed as a standard Class ZZ Plus plug gage for use in go/no-go hole-inspection applications where a nominal diameter of 0.362 inches is specified.

Installation Notes

Plug gages are handled and used by machinists, toolmakers, and quality assurance technicians. Clean the gage and the hole being inspected before use to prevent debris from affecting measurement accuracy. Do not force the gage into a hole; excessive force can damage the gage or the workpiece and will produce unreliable readings. Store the gage in a protective case away from moisture and temperature extremes to maintain calibration integrity.
