Value Collection 364-0185 Hex Rethreading Die M18x2.5

Product Description

The VALUE COLLECTION 364-0185 is a hex rethreading die designed to restore damaged or corroded external metric threads without removing the fastener or fitting from service. Sized for M18x2.5 metric coarse thread, this die is turned over the existing fastener shank using a standard wrench or die stock to clean, reform, and chase threads back to serviceable condition. Constructed from carbon steel, it delivers sufficient hardness for rethreading steel bolts, studs, and threaded rod in mechanical, plumbing, and HVAC applications. Right-hand thread direction matches standard metric fastener convention. Weighing 0.2 pounds, it is a practical addition to any field or shop thread-repair kit.

This rethreading die is suited for maintenance and repair work on M18x2.5 metric coarse threaded fasteners found in mechanical equipment, pipe flanges, structural assemblies, and industrial machinery. It is commonly used by millwrights, pipefitters, HVAC technicians, and general maintenance mechanics who need to recover cross-threaded or rust-damaged bolt threads on-site without a full thread-cutting setup. The hex body style allows use with a standard open-end or adjustable wrench when a dedicated die handle is not available.

Key Features

• M18x2.5 metric coarse thread size for common metric fastener applications
• Right-hand thread direction matches standard metric bolt convention
• Carbon steel construction provides adequate hardness for rethreading steel fasteners
• Hex body profile accepts standard wrenches or die stocks for field use
• Compact and lightweight at 0.2 pounds for inclusion in portable tool kits

Compatibility

Designed as an OEM-style rethreading die for use on M18x2.5 metric coarse external threads on bolts, studs, and threaded rod in standard metric fastener applications.

Installation Notes

Rethreading dies are typically used by mechanics, pipefitters, and maintenance technicians. Before use, de-energize or depressurize any system containing the fastener being serviced. Apply thread-cutting oil to the die and the fastener to reduce friction and extend die life. Turn the die onto the fastener slowly, backing off periodically to clear debris, and avoid forcing the die over severely deformed threads that may require cutting rather than chasing.
