Irwin IR8564ZR Hex Bolt Die 20mm X 2.5 Hcs External

Product Description

The IRWIN IR8564ZR is a hex bolt die designed for cutting and restoring external threads on 20mm fasteners with a 2.5mm pitch. Manufactured from hardened carbon steel (HCS), this die delivers the durability needed for repeated use in demanding shop and field environments. The hex-form outer profile measures 1-13/16 inches across, allowing it to be driven with standard die stocks or wrenches. It is suited for licensed machinists, automotive technicians, and maintenance professionals who need to chase or cut metric external threads efficiently and accurately.

This die is specified for use in automotive repair and general machinery maintenance applications where metric 20mm x 2.5mm threaded fasteners are common. It is appropriate for both restoring damaged threads on existing bolts and cutting new external threads on rod stock. The hardened carbon steel construction makes it a reliable choice for production shop use as well as field repair work where thread integrity is critical to assembly safety.

Installation Notes

Installation and use of threading dies should be performed by a qualified machinist or trade professional familiar with proper thread-cutting technique. Secure the workpiece firmly before engaging the die, and apply cutting fluid to reduce heat and extend die life. Always verify thread pitch and diameter against the fastener specification before cutting to avoid mismatched threads. Inspect the die for wear or chipping before each use.
