Value Collection 364-0042 Hex Rethreading Die M4x0.7

Product Description

The VALUE COLLECTION 364-0042 is a hex rethreading die designed to restore damaged or corroded external metric threads to their original specification. Sized for M4x0.7 thread — a metric coarse pitch commonly found on small fasteners in HVAC equipment panels, electrical enclosures, and plumbing fixtures — this die cuts right-hand threads and is constructed from carbon steel for reliable performance across standard rethreading tasks. It is used by HVAC technicians, electricians, plumbers, and maintenance professionals who need a fast, field-ready solution for salvaging threaded fastener surfaces without full part replacement.

This rethreading die is suited for light industrial and trade service applications where M4 metric coarse fasteners are present. Typical use cases include restoring bolt threads on equipment covers, control board mounting hardware, panel fasteners, and similar small-diameter threaded components. The hex body design allows the die to be driven with a standard wrench or die stock handle, making it practical for both shop and field use.

Key Features

• M4x0.7 thread size restores metric coarse fasteners common in trade equipment
• Right-hand thread direction matches standard fastener orientation
• Carbon steel construction provides adequate hardness for rethreading mild steel and softer fastener materials
• Hex body design accepts standard wrenches or die stock handles for easy driving
• Metric coarse thread standard for broad compatibility with imported and domestic hardware
• Single-piece die — compact and easy to carry in a service kit

Compatibility

Designed as a rethreading die for M4x0.7 metric coarse right-hand threaded fasteners on standard trade and light industrial equipment components.

Installation Notes

Rethreading dies are typically used by qualified tradespeople as part of fastener repair during equipment service. Before use, clean the damaged thread area and apply cutting oil to reduce friction and extend die life. Align the die squarely with the bolt or stud axis before applying torque to avoid cross-threading. Always de-energize equipment and shut off relevant fluid systems before servicing components that require fastener repair.
