Regal Cutting Tools 046200AS Hex Rethreading Die 1/2-13 Unc

Product Description

The REGAL CUTTING TOOLS 046200AS is a hex rethreading die designed to clean and restore damaged or corroded external threads. Built from high-speed steel, this die holds its edge under repeated use and handles the friction generated during thread restoration without premature wear. It is sized for 1/2-13 UNC threads and cuts in a right-hand direction, matching the most common fastener thread standard in general mechanical and industrial work. Machinists, maintenance technicians, and field service professionals reach for this type of die when a bolt or threaded rod has picked up rust, impact damage, or cross-threading that prevents proper nut engagement.

This rethreading die is suited for shop maintenance, equipment repair, and field service applications where restoring existing threads is faster and more practical than replacing a fastener or re-tapping. The 1/2-13 UNC specification covers a wide range of structural fasteners found in industrial equipment, HVAC frames, mechanical assemblies, and general fabrication work. The hex outer profile seats in a standard die stock or wrench for controlled, consistent thread chasing.

Key Features

• High-speed steel construction for durability and edge retention during thread restoration
• 1/2-13 UNC thread size covers common structural and mechanical fastener applications
• Right-hand thread direction matches standard fastener orientation
• Non-adjustable hex body seats securely in a standard die stock or wrench
• Single-piece design with no moving parts to wear or misalign

Compatibility

Designed as an OEM-style replacement hex rethreading die for use with standard die stocks and wrenches sized to accept a hex-body die in 1/2-13 UNC right-hand thread configuration.

Installation Notes

Thread chasing and rethreading work is typically performed by machinists or maintenance technicians using a properly sized die stock or adjustable wrench. Before use, clean the damaged threads of debris, rust, and oil to allow the die to track correctly. Apply cutting oil to the die and the workpiece threads to reduce heat buildup and extend tool life. Secure the workpiece firmly before applying torque to prevent movement that can cause the die to cross-thread.
