Spi 23-196-9 Truncated Taperlock Thread Plug Gage 3/4-16 Unf

Product Description

The SPI 23-196-9 is a truncated taperlock thread plug gage used to verify internal thread dimensions to 3/4-16 UNF tolerances. It provides both Go and No Go checks in a single set, confirming that a threaded bore falls within Class 2A acceptance limits. The gage is machined from tool steel for wear resistance and dimensional stability. It ships with a 3-inch handle sized for standard taperlock gage handle systems. Machinists, quality inspectors, and tool room technicians use this gage during in-process and final inspection of threaded components.

This gage is suited for shop floor and inspection room use wherever 3/4-16 UNF internal threads require verification against Class 2A tolerance limits. Typical applications include production inspection of threaded bores in machined parts, assemblies, and fastener-receiving components. The truncated thread form reduces gage wear during high-volume inspection cycles compared to full-form plug gages. The taperlock design allows quick replacement of the gage members without replacing the handle.

Key Features

• Go and No Go members included for complete Class 2A thread verification in a single gage set
• Truncated thread form extends gage service life during repetitive inspection use
• Taperlock design allows worn gage members to be replaced independently of the handle
• Tool steel construction provides hardness and dimensional stability under continuous use
• Includes a 3-inch handle compatible with standard taperlock handle systems
• UNSPSC Code 41111619 for procurement and cataloging systems

Compatibility

Designed for use with standard taperlock-style gage handles. Gage members are sized for 3/4-16 UNF Class 2A internal thread inspection and are compatible with taperlock handle systems accepting members of this series.

Installation Notes

Thread plug gages are installed and removed by hand — no power tools or torque application. Before use, clean the gage members and the threaded bore to remove chips, oil, or debris that could affect the reading. Handle and gage member connections should be checked for tightness before each inspection session. Gages should be stored per the manufacturer recommendation to prevent corrosion and dimensional drift.
