Spi 23-210-8 Thread Plug Gage 1-14 Uns Go No Go

Product Description

The SPI 23-210-8 is a truncated taperlock thread plug gage used to verify internal thread quality to Class 2A tolerances on 1-14 UNS threads. It includes both Go and No Go members, allowing technicians and machinists to confirm that threaded holes fall within acceptable dimensional limits in a single tool set. The gage is manufactured from tool steel for wear resistance and dimensional stability, and it comes with a 4-inch handle for secure handling during inspection. This type of precision gage is standard equipment in manufacturing, machining, and quality-control environments where thread acceptance criteria must be documented and repeatable.

The 23-210-8 is designed for use on unified national special (UNS) threads at 1-14 designation. It is suited to production floor inspection, incoming inspection, and in-process thread verification on machined components. The truncated taperlock design allows the Go and No Go gaging members to seat securely into a standard taperlock handle, reducing handling time and keeping the inspection workflow efficient. This gage is typically used by quality inspectors, machinists, and tooling technicians in industrial and manufacturing settings.

Key Features

• Go and No Go members included for complete Class 2A thread acceptance inspection
• Truncated taperlock design seats firmly in standard taperlock handles
• Tool steel construction provides hardness and dimensional stability under repeated use
• 4-inch handle included for comfortable, controlled gage operation
• Covers 1-14 UNS thread specification for unified national special applications

Compatibility

Designed as an OEM-style inspection gage for use with standard taperlock handle systems on 1-14 UNS threaded components requiring Class 2A acceptance verification.

Installation Notes

Thread plug gages are inspection tools and do not require permanent installation. Ensure the taperlock members are fully seated and secure in the handle before use. Clean both the gage and the threaded bore of chips, coolant, and debris before gaging to prevent false readings or premature gage wear. Gages should be stored in a protective case when not in use and periodically calibrated against master setting plugs to maintain traceable accuracy.
