Value Collection 367-0402 Hex Rethreading Die 5/8-18 Hss

Product Description

The VALUE COLLECTION 367-0402 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Machined from high-speed steel, this die holds its cutting edge under the friction and heat generated during thread chasing on hard or work-hardened fasteners. The 5/8-18 UNF thread profile and right-hand direction make it a direct match for fine-pitch inch-series threaded fasteners common in mechanical, plumbing, and HVAC assembly work. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics keep rethreading dies on hand for field repair of bolts, studs, and fittings without full disassembly.

This die is suited for rethreading 5/8-18 UNF right-hand external threads on bolts, rod ends, valve stems, and similar hardware. The hex outer profile accepts a standard rethreading die wrench or adjustable wrench, making it practical for confined spaces where a round die stock cannot be used. It is appropriate for use on steel, stainless steel, brass, and other machinable metals encountered in trade service work.

Key Features

• 5/8-18 UNF thread size for fine-pitch inch-series fastener repair
• High-speed steel construction for extended cutting life on hard materials
• Right-hand thread direction matches standard inch-series hardware
• Hex outer profile accepts a standard wrench for use without a dedicated die stock
• Single-piece construction with no adjustable components to lose or reset in the field

Compatibility

Designed for rethreading 5/8-18 UNF right-hand external threads on bolts, studs, and threaded rod commonly found in mechanical and trade service applications.

Installation Notes

Rethreading dies are typically used by licensed plumbers, HVAC technicians, and maintenance mechanics during equipment service or repair. Before use, clean the damaged thread area of debris and apply a cutting oil to reduce heat and extend die life. Start the die straight onto the fastener to avoid cross-threading, and back off periodically to clear chips. Do not use a rethreading die as a cutting die for forming new threads on unthreaded stock.
