Value Collection 366-1331 Hex Rethreading Die 1-5/8-12

Product Description

The VALUE COLLECTION 366-1331 is a hex rethreading die designed to restore damaged or corroded external threads without removing the fastener or fitting from service. It cuts a left-hand, 1-5/8-12 UNS thread profile and measures 1 inch thick. Machined from carbon steel, it delivers the hardness needed to clean and recut threads on bolts, studs, and threaded rod in demanding shop or field conditions. Machinists, maintenance technicians, and trade professionals reach for rethreading dies when threads are galled, rusted, or cross-threaded and a full replacement is not practical.

This die is suited for rethreading applications where a left-hand 1-5/8-12 UNS thread standard is required. Left-hand thread configurations appear in specific mechanical assemblies, rotating equipment, and certain plumbing and HVAC fittings where counter-rotation would loosen a standard right-hand fastener. The die fits standard hex die stocks that accept its hex outer profile, making it compatible with common workshop and field tooling setups.

Key Features

• 1-5/8-12 UNS thread size for precise thread restoration to specification
• Left-hand thread direction for assemblies requiring reverse-thread fasteners
• 1 inch thickness provides added body for stability during cutting
• Carbon steel construction delivers hardness suitable for rethreading ferrous and softer metals
• Hex outer profile fits standard die stocks for easy handling and torque application

Compatibility

Designed as an OEM-style replacement die for use in standard hex die stocks accepting a 1-5/8-12 left-hand UNS rethreading die.

Installation Notes

This die is installed and operated by machinists or experienced trade technicians using a compatible hex die stock. Secure the workpiece before threading to prevent movement and ensure accurate thread alignment. Apply cutting oil to the die and workpiece threads before use to reduce friction and extend die life. Never force the die past resistance — back off periodically to clear chips and prevent binding.
