The Irwin 25701 Hexagon Re-threading Die Set (HCS) provides professional technicians and mechanics with a robust solution for restoring damaged or stripped external threads on bolts, studs, and various fasteners. This 10-piece set is engineered from high-carbon steel for durability and precision, ensuring reliable thread repair in demanding automotive and industrial environments. It's a critical tool for maintaining the integrity of existing hardware without the need for costly replacements.

Key Features

• Comprehensive 10-Piece Set: Includes essential UNC (Unified National Coarse) re-threading dies for 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", and 1" fasteners, offering broad application coverage.
• High-Carbon Steel Construction: Manufactured from hardened high-carbon steel, these dies are built for extended life and consistent performance under professional use.
• Hexagonal Design: The hexagon shape allows for use with standard wrenches or sockets, providing flexibility and access for repairing threads in confined or hard-to-reach areas.
• Optimized for Re-threading: These dies are specifically designed to clean and reshape existing threads rather than cut new ones, helping to maintain the original strength and profile of roll-formed fasteners.
• Protective Storage Case: Comes with a durable case for organized storage and easy transport, protecting the dies from damage and loss.

Applications

The Irwin 25701 Hexagon Re-threading Die Set is indispensable for a wide range of professional applications. It is ideal for repairing damaged threads on engine components, transmission housings, chassis fasteners, and suspension systems in automotive repair. Industrially, this set is valuable for maintenance and repair of heavy machinery, agricultural equipment, construction vehicles, and other mechanical assemblies where preserving original fasteners is critical. It efficiently restores threads compromised by corrosion, cross-threading, or impact, enabling proper torque and secure assembly.
