Value Collection 366-1162 Hex Rethreading Die 1-1/4-12 Unf

Product Description

The VALUE COLLECTION 366-1162 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, bolts, and fittings. Manufactured from carbon steel, this die handles 1-1/4-12 UNF left-hand threads and measures 1 inch thick. Rethreading dies like this one are standard shop and field tools used by mechanics, pipefitters, and maintenance technicians to clean up thread profiles without full replacement of the fastener. The hex body allows drive with a standard wrench or die stock for controlled, repeatable thread restoration.

This die is suited for rethreading left-hand UNF fasteners and threaded components found in mechanical assemblies, rotating equipment, and specialty hardware applications where left-hand thread configurations are specified. It is appropriate for both bench use in a shop environment and field repair situations where thread damage has occurred due to corrosion, impact, or installation error.

Key Features

• 1-1/4-12 UNF thread specification for fine-pitch left-hand thread restoration
• Left-hand thread direction for use on components requiring reverse-thread fasteners
• Carbon steel construction provides hardness suitable for rethreading steel and softer alloy fasteners
• 1 inch thickness gives adequate contact length for full thread profile engagement
• Hex outer profile compatible with standard wrenches and die stocks

Compatibility

Designed as a rethreading die for 1-1/4-12 UNF left-hand externally threaded fasteners and components. Verify thread standard, direction, and pitch before use.

Installation Notes

Rethreading dies are used by machinists, pipefitters, and mechanical maintenance technicians. Before use, clean the damaged threads of debris and apply cutting oil to reduce friction and heat buildup. Align the die squarely on the fastener before applying torque to avoid cross-threading or further damage. Always confirm left-hand thread direction on the workpiece before proceeding, as applying a left-hand die to a right-hand thread will cause additional damage.
