Value Collection 315-1252 Round Die 5/8-16 Hss Adjustable

Product Description

The VALUE COLLECTION 315-1252 is a round threading die designed to cut external threads on bolts, rods, and fasteners. Sized for a 5/8-16 thread form, it follows the Unified National Special (UNS) standard with a right-hand thread direction. The die is machined from high-speed steel (HSS), which holds a cutting edge under the heat and friction generated during threading operations. An adjustable design allows the cutting diameter to be fine-tuned for fit tolerance and thread quality. This die is used by machinists, pipefitters, maintenance mechanics, and general metalworkers performing threading tasks in shop or field environments.

This die is suited for threading mild steel, stainless, aluminum, and other machinable metals in both production and repair applications. The 5/8-16 designation indicates a 5/8-inch nominal diameter with 16 threads per inch, making it appropriate for custom fastener fabrication, rod threading, and rework of damaged threads. It fits standard round die stocks compatible with its die outside diameter. Individual packaging makes it practical for single-die replacement without purchasing a full set.

Key Features

• 5/8-16 thread size for UNS-standard external threading
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable die body allows fine-tuning of thread fit and cutting diameter
• Right-hand thread direction for standard fastener applications
• Single-piece packaging suitable for direct replacement or kit supplementing

Compatibility

Designed as an OEM-style replacement or direct-use round die for standard round die stocks that accept the appropriate outside diameter, used in threading operations requiring a 5/8-16 UNS right-hand thread form.

Installation Notes

Round dies are installed by machinists and metalworkers using a compatible round die stock or die holder. Secure the die firmly in the stock before use and apply cutting oil throughout the threading process to extend die life and improve thread quality. Always start the die square to the workpiece to avoid crooked or damaged threads. Wear appropriate eye and hand protection when operating threading tools.
