Cle-line C65630 Hex Rethreading Die 1-3/8-6 Unc

Product Description

The CLE-LINE C65630 is a hex rethreading die designed to restore damaged or corroded external threads on bolts, studs, and threaded rod. It cuts a 1-3/8-6 UNC right-hand thread profile and measures 1 inch thick. Manufactured from carbon steel, this die delivers the hardness needed to chase and clean threads on standard fastener materials. It is a non-adjustable, fixed-profile die intended for quick field or shop rethreading work. Machinists, maintenance technicians, and trade professionals use this die when a fastener thread is too damaged for a nut to run cleanly but the fastener itself does not need full replacement.

This die is suited for rethreading applications in industrial maintenance, mechanical contracting, and general fabrication. It handles the 1-3/8-6 UNC thread standard, which appears on large-diameter structural bolts and heavy equipment fasteners. The hex outer profile seats into a standard die stock handle, making it practical for both bench use and in-place field rethreading where space allows. It is a single-quantity item with no minimum order beyond one piece.

Key Features

• 1-3/8-6 UNC thread profile for large-diameter fastener rethreading
• Right-hand thread direction - compatible with standard bolt and stud orientation
• Carbon steel construction provides adequate hardness for chasing threads on common fastener materials
• 1 inch thick hex die body fits standard die stock handles
• Non-adjustable fixed profile for consistent thread form on every pass

Compatibility

Designed as an OEM-style replacement or direct-use rethreading die for standard die stock handles accepting hex dies in the 1-3/8 inch thread size range. Compatible with UNC thread standard fasteners only.

Installation Notes

A licensed machinist or qualified maintenance technician should perform rethreading operations. Secure the workpiece firmly before applying the die to prevent movement that can cross-thread or damage the die. Apply cutting oil to the die and fastener before and during use to reduce heat and extend die life. Do not use this die to cut threads from unthreaded blank stock - it is rated for rethreading and thread restoration only.
