Value Collection 366-0202 Hex Rethreading Die 5/16-24 Lh

Product Description

The VALUE COLLECTION 366-0202 is a hex rethreading die designed to restore damaged or corroded external threads without the need for a full tap-and-die set. Sized for 5/16-24 left-hand UNF threads, it removes burrs, straightens distorted thread flanks, and brings fastener threads back to serviceable condition. Made from carbon steel, the die delivers adequate hardness for rethreading mild steel fasteners and common hardware. The hex body accepts a standard hex wrench or rethreading die holder, keeping the tool stable during use. Machinists, mechanics, and maintenance technicians keep this type of die in their toolbox for field repair and bench work.

This rethreading die is suited for applications where left-hand threaded fasteners are standard, such as certain mechanical assemblies, rotating equipment, and specialty hardware where reverse-thread fasteners are used to prevent loosening under rotation. It is appropriate for use on bolts, studs, and threaded rod with a 5/16-24 UNF left-hand thread form. Typical users include maintenance mechanics and industrial technicians performing thread restoration on existing hardware rather than cutting new threads from scratch.

Key Features

• 5/16-24 UNF left-hand thread specification for restoring reverse-thread fasteners
• Carbon steel construction provides adequate hardness for rethreading mild steel hardware
• Hex body design accepts standard hex wrenches and rethreading die holders
• Restores damaged or corroded external threads without replacing the fastener
• Compact size suits toolbox storage for field and bench use

Compatibility

Designed as an OEM-style replacement or direct-use rethreading die for 5/16-24 left-hand UNF threaded fasteners in mechanical and industrial maintenance applications.

Installation Notes

A licensed mechanic or qualified maintenance technician should confirm the existing thread form matches 5/16-24 UNF left-hand before use. The fastener and die should be properly aligned to avoid cross-threading or further thread damage. Apply a thread-cutting lubricant to the fastener before running the die to reduce friction and extend die life. Turn the die in the left-hand direction, consistent with the thread orientation, using steady and controlled pressure.
