Spi 34-654-4 Plug Thread Gage Handle Size 2 Steel

Product Description

The SPI 34-654-4 is a size 2 plug thread gage handle designed for use with plug thread gages in inspection and quality control applications. Constructed from steel, this handle provides a durable, rigid grip for accurate thread verification across multiple thread sizes ranging from 3/8 inch to 1/2 inch. Compatible with both coarse and fine pitch threads, it is suited for production floor use, incoming inspection, and machine shop quality checks. A Certification of Inspection traceable to ANSI and NIST standards is included with each unit, supporting documentation requirements in regulated manufacturing environments.

This handle is used in manufacturing, machining, and quality assurance settings where plug thread gages must be applied consistently and safely. Handle size 2 accommodates a range of standard thread gage blanks commonly encountered in light to medium industrial threading applications. Machinists, quality control inspectors, and toolroom technicians are the primary installers and users of this component. Supported plug thread sizes include 1/2-13, 1/2-20, 1/2-28, 3/8-16, 3/8-24, 3/8-32, 7/16-14, 7/16-20, and 7/16-28.

Installation Notes

Thread gage handles are installed and used by machinists, toolroom technicians, and quality control inspectors. Ensure the gage blank is fully seated and secured in the handle before applying to a workpiece. Do not use gage handles as torque or assembly tools. Store gages and handles in a clean, dry environment to prevent corrosion and preserve calibration integrity.
