Irwin 9734 Hex Die 8mm X 1.25 Metric Carbon Steel

Product Description

The IRWIN INDUSTRIAL TOOL CO 9734 is a metric hexagon die designed for hand threading work across a wide range of materials. The die measures 8mm x 1.25 and features a 1-inch hex body machined from carbon steel. It is intended for routine maintenance and repair work where a high-accuracy tolerance thread is not the primary requirement, such as rethreading damaged fasteners or cleaning existing threads. Licensed tradespeople and maintenance technicians across plumbing, HVAC, and general industrial settings reach for this die when a quick, reliable thread repair is needed without specialty tooling.

This die is well suited for field service and shop maintenance applications. Its hex body allows it to be driven with a standard wrench or socket when working in confined or restricted spaces where a traditional die stock cannot fit. For open-work applications, it is recommended for use with a compatible hexagon die stock for better control and torque application. The 8mm x 1.25 metric specification covers one of the most common thread pitches found on metric fasteners used in mechanical, HVAC, and plumbing systems worldwide.

Key Features

• 8mm x 1.25 metric thread specification for one of the most common metric fastener sizes
• 1-inch hex body compatible with standard wrenches and sockets for use in tight spaces
• Carbon steel construction provides adequate hardness for hand threading in a variety of materials
• Recommended for use with a hexagon die stock for improved control during threading
• Suited for rethreading, repair, and routine maintenance where precision tolerance is not critical
• Package includes 3 units per pack

Compatibility

Designed for use with standard hexagon die stocks that accept a 1-inch hex die body. The die can also be driven directly with a wrench or socket of matching size when clearance is limited.

Installation Notes

This die is intended for hand threading use only and should not be used in powered threading equipment. Before rethreading a fastener or fitting, ensure the workpiece is secure and deburr any damaged thread area as needed. Apply a suitable cutting oil or threading lubricant to extend die life and improve thread quality. Always power down or depressurize any system before working on threaded connections in live plumbing or HVAC piping.
