Irwin 9331ZR 10-32 Nf Hex Machine Screw Die 1 Inch Carbon Steel

Product Description

The IRWIN INDUSTRIAL TOOL CO 9331ZR is a 10-32 National Fine thread hexagonal machine screw die made from carbon steel. It measures 1 inch across the hex and is designed for hand threading operations in a wide range of materials. This die is suited for routine maintenance and repair work where rethreading is needed and high-accuracy tolerance is not the primary requirement. It is a standard tool for plumbers, electricians, HVAC techs, pipefitters, and general maintenance professionals who need to chase or cut 10-32 NF threads in the field or shop.

The 9331ZR is intended for hand threading tasks across metal, plastic, and similar workpiece materials. Its hexagonal body is designed for use with a standard hex die stock, and it can also be driven with a wrench or socket when working in confined or limited-clearance spaces. This makes it practical for in-place rethreading of machine screws, fasteners, and threaded rod without requiring a threading machine or bench setup.

Installation Notes

Install this die into a hex die stock or grip it with an appropriately sized wrench or socket before use. Secure the workpiece firmly before threading to ensure consistent thread engagement. Apply cutting oil to the workpiece and die when threading metal to reduce heat and extend die life. This is a hand threading tool and is not intended for use with power threading equipment.
