Value Collection 750009 Hex Rethreading Die 5/16-24

Product Description

The VALUE COLLECTION 750009 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. It cuts a 5/16-24 UNF thread profile in the right-hand direction and is made from carbon steel for reliable performance on standard fastener repair tasks. The 1-inch hex body seats securely in a standard die stock or wrench, allowing controlled torque application. Plumbers, pipefitters, HVAC technicians, and general maintenance professionals use this type of die to salvage threaded fittings, bolts, and studs rather than replacing them outright.

This rethreading die is suited for field and shop repair work where 5/16-24 UNF threads have been damaged by corrosion, cross-threading, or impact. Common applications include restoring threads on HVAC equipment fasteners, plumbing fixture hardware, and mechanical assembly components. The right-hand thread direction matches the standard orientation found on the vast majority of inch-series threaded fasteners encountered in trade work.

Key Features

• 5/16-24 UNF thread size for restoring fine-pitch inch-series threads
• Right-hand thread direction compatible with standard fastener orientation
• 1-inch hex body fits standard die stocks and adjustable wrenches
• Carbon steel construction provides adequate hardness for thread repair on common fastener materials
• Compact form factor suited for tight spaces and field service use

Compatibility

Designed as an OEM-style replacement rethreading die for use on 5/16-24 UNF externally threaded fasteners and fittings across residential and light commercial trade applications.

Installation Notes

This die is installed and operated by hand using a properly sized die stock or wrench — no power tools are required or recommended for rethreading operations. Clean and degrease the damaged thread before use, and apply a suitable cutting fluid to reduce friction and extend die life. Thread the die onto the fastener slowly, backing off periodically to clear chips. Always verify thread pitch with a thread gauge before and after rethreading to confirm the repair meets specification.
