Value Collection 367-0161 Hex Rethreading Die 1/4-20 Hss

Product Description

The VALUE COLLECTION 367-0161 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Made from high-speed steel, this die handles the friction and heat generated during thread restoration without premature wear. It cuts a 1/4-20 UNC right-hand thread profile, which is one of the most common inch-series fastener standards in mechanical, HVAC, plumbing, and electrical work. Technicians reach for rethreading dies when bolt threads are galled, rusted, or cross-threaded and full replacement is not practical. The hex body accepts a standard wrench for controlled torque application.

This die is suited for job-site repair and shop maintenance work across a wide range of trades. Anywhere a 1/4-20 UNC fastener is used, this tool can clean and restore the thread form without requiring complete disassembly or part replacement. Common applications include restoring threads on equipment housing bolts, access panel fasteners, and mechanical components encountered in HVAC, refrigeration, and general mechanical service.

Key Features

• 1/4-20 UNC thread size covers one of the most widely used inch-series fastener standards
• High-speed steel construction resists heat and wear during thread restoration cuts
• Right-hand thread direction matches standard fastener orientation
• Hex body profile accepts a standard wrench or die stock for controlled application
• Rethreading geometry cleans and reforms existing threads rather than cutting new stock

Compatibility

Designed for use on external 1/4-20 UNC right-hand threaded fasteners and components. Suitable for thread restoration on steel, iron, aluminum, and similar materials where 1/4-20 UNC fasteners are specified.

Installation Notes

Use by licensed mechanics, HVAC technicians, plumbers, or electricians performing field thread repair. Before rethreading, de-energize any equipment and relieve system pressure per standard lockout/tagout procedures. Apply cutting oil to the die before engaging the threads to reduce friction and extend tool life. Do not force the die onto severely deformed threads — straighten or file the thread lead-in first to avoid die damage.
