Value Collection 366-1242 Hex Rethreading Die 1-3/8-12

Product Description

The VALUE COLLECTION 366-1242 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and fittings. Built from carbon steel, this die handles the physical demands of rethreading work in shop or field environments. It is configured for 1-3/8-12 UNF threads and features a left-hand thread direction, making it the correct tool for left-hand threaded applications where a standard right-hand die would not produce usable results. At 1 inch thick, the die provides adequate engagement length for clean thread restoration. Machinists, millwrights, and maintenance technicians are the primary users of this type of tooling.

This rethreading die is suited for maintenance and repair operations where existing left-hand UNF threads on bolts, rods, or mechanical components have been damaged, crossed, or corroded. It is used in manufacturing facilities, machine shops, and industrial maintenance settings where left-hand threaded hardware is specified for anti-loosening or directional load requirements. The 1-3/8-12 UNF specification targets fine-pitch applications where thread integrity is critical to joint performance.

Key Features

• 1-3/8-12 UNF thread specification for fine-pitch left-hand thread restoration
• Left-hand thread direction for use on counter-threaded fasteners and components
• Carbon steel construction provides durability for rethreading and chasing operations
• Hex outer profile accepts standard die stocks and wrenches for controlled torque application
• 1 inch thickness provides sufficient engagement for consistent thread form

Compatibility

Designed for use with standard hex die stocks sized to accept a 1-3/8-12 hex rethreading die. Intended for left-hand UNF threaded fasteners and components requiring thread restoration or chasing.

Installation Notes

This die is installed and operated by machinists or qualified maintenance technicians using a compatible hex die stock. Ensure the workpiece is secured in a vise or fixture before beginning thread chasing to prevent movement. Apply cutting oil to the die and workpiece to reduce heat and improve thread quality. Verify thread direction before use — this die cuts left-hand threads and will not produce correct results on standard right-hand threaded fasteners.
