Value Collection 365-3484 Hex Rethreading Die 3-3/4 Unc

Product Description

The VALUE COLLECTION 365-3484 is a hex rethreading die designed to restore damaged or corroded external threads to their original specifications. Built from carbon steel, this die handles 3-3/4-4 UNC thread size with a right-hand thread direction. The 6-inch hex body provides a secure grip for standard wrenches and die stocks, allowing controlled torque application during rethreading operations. Machinists, pipefitters, and maintenance technicians use this type of die when field repairs require restoring thread integrity on bolts, studs, or threaded rod without full replacement.

This rethreading die is suited for maintenance, repair, and operations (MRO) work across industrial, mechanical, and plumbing applications where large-diameter UNC fasteners are in service. It is used in both shop and field environments where damaged threads on heavy fasteners need to be cleaned and restored. The right-hand thread direction matches standard UNC fastener conventions, making it compatible with the majority of inch-series threaded components encountered in industrial maintenance work.

Key Features

• 3-3/4-4 UNC thread specification for large-diameter fastener rethreading
• Right-hand thread direction matches standard UNC fastener convention
• 6-inch hex body accommodates standard wrenches and die stocks for controlled torque
• Carbon steel construction provides durability for heavy-duty rethreading tasks
• Single-piece die format for straightforward field and shop use

Compatibility

Designed as an OEM-style rethreading die for 3-3/4-4 UNC right-hand threaded fasteners and components in industrial and mechanical maintenance applications.

Installation Notes

This die is installed and operated by machinists, pipefitters, or qualified maintenance technicians familiar with thread repair procedures. Before use, clean the damaged threads and apply appropriate cutting oil to reduce friction and extend die life. Secure the workpiece firmly before applying the die to prevent movement during rethreading. Follow standard shop safety practices and wear appropriate hand and eye protection when performing thread repair operations.
