The IRWIN IR8568 is a hex bolt die designed for cutting and restoring external 24mm x 2.0mm metric threads. Manufactured from hardened carbon steel (HCS), this die delivers the rigidity needed for clean, accurate thread formation on bolts and fasteners. The hex outer profile measures 1-13/16 inches across and is sized for use with standard external die stocks. It is a practical hand tool for licensed machinists, automotive technicians, and maintenance tradespeople who need to cut new threads or chase damaged ones on metric fasteners.
This die is suited for automotive repair shops, industrial machinery maintenance, and general metalworking applications where 24mm x 2.0mm metric external threads are required. It is sold individually and can be used as a standalone replacement die or as part of a thread-cutting set. Typical use cases include restoring corrosion-damaged fastener threads and threading new rod or bolt stock to metric specification.
Designed as an OEM-style replacement or standalone hex die for use with external die stocks that accept a 1-13/16 inch hex die, cutting 24mm x 2.0mm metric external threads.
Thread-cutting dies should be installed and operated by qualified machinists or experienced tradespeople familiar with hand threading tools. Ensure the workpiece is securely clamped before applying the die stock. Apply cutting oil to the die and workpiece to reduce heat and extend die life. Always inspect the die for chips or wear before use to ensure accurate thread form.
