Value Collection 314-4260 Round Die 1/2-13 Unc Left Hand Hss

Product Description

The VALUE COLLECTION 314-4260 is a round threading die machined from high-speed steel for cutting external left-hand threads. It is designed to cut a 1/2-13 UNC thread profile and features an adjustable split-body construction that allows the operator to fine-tune the thread fit by closing or opening the die with a set screw before the final pass. High-speed steel construction gives the die the hardness and heat resistance needed to thread mild steel, stainless, brass, and similar materials at production-appropriate feed rates. This die is suited for machine shops, maintenance facilities, and field service operations where left-hand threaded fasteners are required.

This die is used whenever a left-hand external thread must be cut or re-chased on a 1/2-inch diameter workpiece with a 13 threads-per-inch pitch. Typical applications include fabricating replacement spindles, tie-rod ends, turnbuckles, and other assemblies that use left-hand threads as a functional anti-loosening feature. The round die format fits standard die stocks sized for 1-inch outside-diameter round dies.

Key Features

• 1/2-13 UNC left-hand thread profile for cutting reverse-direction external threads
• High-speed steel construction provides hardness and wear resistance across a range of workpiece materials
• Adjustable split body allows thread tolerance to be dialed in during the cutting process
• Round die format fits standard 1-inch OD die stocks commonly found in trade and shop toolkits
• Single-piece packaging suitable for individual replacement or toolbox restocking

Compatibility

Designed for use with standard die stocks and die holders that accept a round die. Cuts 1/2-13 UNC left-hand external threads on compatible workpiece materials.

Installation Notes

Secure the workpiece firmly in a vise before threading. Use a properly sized die stock that matches the outside diameter of this round die, and apply cutting oil throughout the operation to extend die life and improve thread finish. Advance the die in short increments and back off periodically to clear chips, especially on ferrous materials. Inspect the finished thread with a left-hand gauge nut before assembly.
