Spi 29-234-2 Class Zz Plus Plug Gage 0.234 in Dia

Product Description

The SPI 29-234-2 is a Class ZZ Plus plug gage designed to verify bore and hole diameters to a nominal size of 0.234 inches with a tolerance of 0.0002 inches. Plug gages of this class are go/no-go inspection tools used to confirm that machined holes fall within specified dimensional tolerances. The 29-234-2 is machined from steel, providing the hardness and wear resistance required for repeated use in production and quality-control environments. Machinists, toolmakers, and quality technicians use these gages on lathes, mills, and inspection tables to validate hole dimensions before assembly or shipment.

This gage is suited for use in machine shops, manufacturing facilities, and precision fabrication environments where hole diameter verification is part of standard inspection workflow. It is appropriate for both production-floor spot checks and formal inspection station use. The 0.234-inch nominal diameter makes it a common selection for small-bore inspection tasks in metalworking and mechanical assembly operations.

Key Features

• Nominal measurement diameter of 0.234 inches for small-bore inspection
• Class ZZ Plus tolerance rating of 0.0002 inches for precise dimensional verification
• Steel construction for hardness and long service life under repeated use
• Go/no-go style inspection tool compatible with standard quality-control workflows
• Single-piece package quantity suitable for individual station or toolbox use

Compatibility

Designed as an OEM-style replacement or equivalent plug gage for use in any application requiring inspection of 0.234-inch nominal diameter bores to Class ZZ Plus standards.

Installation Notes

Plug gages are inspection instruments 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 other metal tooling to avoid surface damage. Follow your facility's gage calibration and handling procedures to maintain measurement accuracy.
