This professional-grade tool is specifically designed to repair and restore damaged, corroded, or cross-threaded external threads on bolts, studs, and threaded rods without cutting new threads.

Key Features:

• 7/8"-14 UNF thread size for fine pitch applications
• Hexagonal shape allows use with standard wrenches and sockets
• Carbon steel construction for strength and durability
• Perfect for automotive, industrial, and maintenance applications

Hex rethreading dies are essential tools for mechanics, fabricators, and maintenance professionals who need to salvage threaded fasteners damaged by rust, corrosion, or impact. The hex design provides easy access in tight spaces where traditional round dies and die stocks cannot fit, making this tool invaluable for automotive spindle and axle repair work.
