Value Collection 314-4372 Round Die 3/4-16 2in Od Hss Left Hand

Product Description

The VALUE COLLECTION 314-4372 is a round threading die designed to cut external left-hand threads on cylindrical stock. It measures 2 inches in outside diameter and cuts a 3/4-16 UNF thread profile. Manufactured from high-speed steel (HSS), the die maintains cutting-edge hardness through the heat generated during threading operations. The adjustable design allows the machinist to control thread fit by opening or closing the die slightly with a set screw, enabling both roughing and finishing passes without changing tools. This die is used in a standard round die stock holder and is appropriate for job-shop, maintenance, and production threading work.

This die is suited for applications requiring left-hand external threads on bolts, studs, and threaded rod in the 3/4-16 UNF specification. Left-hand thread dies are commonly used in applications where counter-rotation would loosen a standard right-hand fastener, such as certain spindle assemblies, turnbuckles, and specialized mechanical linkages. Machinists, tool-and-die workers, and maintenance mechanics working in industrial, HVAC equipment, and mechanical assembly environments will find this die useful for repair and fabrication tasks.

Key Features

• 3/4-16 UNF thread size for fine-pitch external threading
• Left-hand thread direction for counter-rotation fastening applications
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable design allows thread fit tuning without changing dies
• 2 inch outside diameter fits standard round die stock holders

Compatibility

Designed as a replacement or additional round die for standard 2 inch round die stock holders used in machining and threading operations.

Installation Notes

This die is installed and secured in a compatible round die stock holder using the holder's set screws before use. Ensure the workpiece is properly secured in a vise or fixture before threading begins. Apply cutting fluid generously to the die and workpiece to reduce heat buildup and extend tool life. Back off the die periodically during threading to break the chip and prevent binding.
