Value Collection 314-1246 Round Die 5/16-24 Unf Hss

Product Description

The VALUE COLLECTION 314-1246 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. Sized for 5/16-24 UNF thread form, it produces right-hand threads in a single setup. The die body is machined from high-speed steel, which retains cutting-edge hardness under the friction and heat generated during threading operations. An adjustable design allows the operator to set cutting depth for initial passes or finishing cuts. This die is a standard tool for machinists, maintenance technicians, plumbers, and pipefitters working with fine-thread fastener stock in shop or field environments.

This die is suited for threading mild steel, aluminum, brass, and similar materials where 5/16-24 UNF external threads are required. Typical applications include fabricating or repairing threaded rod, restoring damaged fastener threads, and producing custom bolt lengths in maintenance, manufacturing, and mechanical service settings. The 5/16-24 UNF standard is common in automotive, HVAC equipment assembly, and precision mechanical assemblies where a fine thread pitch provides greater holding strength than coarse-thread equivalents.

Key Features

• 5/16-24 UNF thread size for fine-pitch external threading
• High-speed steel construction for durability under cutting friction and heat
• Right-hand thread direction — standard orientation for most fastener applications
• Adjustable die body allows control over thread depth and cutting passes
• Round die form fits standard die stocks and handles

Compatibility

Designed as a standard round die compatible with die stocks and handles sized to accept this die body. Fits threading applications requiring 5/16-24 UNF external thread specification.

Installation Notes

Use with a properly sized round die stock to maintain control and apply even pressure during threading. Secure the workpiece firmly in a vise before beginning cuts. Apply cutting oil throughout the threading operation to reduce heat buildup and extend die life. Reverse the die a half-turn periodically to clear chips and prevent thread damage.
