Value Collection 314-4152 Round Die 7/16-14 1in Od Hss Left Hand

Product Description

The VALUE COLLECTION 314-4152 is a round threading die designed to cut external left-hand threads on rod, bolt stock, and fastener blanks. Manufactured from high-speed steel (HSS), it holds a cutting edge under the heat and friction generated during threading operations. The die measures 1 inch in outside diameter and cuts a 7/16-14 thread profile conforming to the Unified National Coarse (UNC) standard. An adjustable design allows the operator to fine-tune thread fit and compensate for minor wear, extending the usable life of the die. Weighing 0.5 pounds, it is sized for standard 1-inch round die stocks and hand threading frames.

This die is suited for machine shops, maintenance departments, and field repair applications where left-hand threaded fasteners must be fabricated or restored. Left-hand thread dies see regular use in applications where counter-rotation would loosen a conventional right-hand thread, such as certain bicycle components, turnbuckles, and mechanical linkages. The 7/16-14 UNC designation makes it compatible with common fractional threading work in automotive, industrial, and general mechanical trades.

Key Features

• High-speed steel construction retains cutting hardness through repeated use
• Left-hand thread direction for counter-rotation fastener applications
• 7/16-14 UNC thread profile for standard fractional work
• Adjustable design allows thread fit tuning and extends service life
• 1 inch outside diameter fits standard round die stocks

Compatibility

Designed as an OEM-style replacement or supplemental die for use in standard 1-inch round die stocks and threading frames accepting 1-inch OD round dies.

Installation Notes

Round dies are installed and secured in a matching die stock using set screws before threading begins. Machinists and maintenance technicians should apply cutting fluid to the workpiece before and during threading to reduce heat buildup and improve thread finish. Ensure the workpiece is held securely in a vise and that the die stock is started square to the stock to avoid cross-threading. Adjust die opening as needed using the adjustment screw before cutting the final thread pass.
