Value Collection 367-0202 Hex Rethreading Die 5/16-24 Hss

Product Description

The VALUE COLLECTION 367-0202 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and fittings. The die is ground from high-speed steel (HSS), which maintains a sharp cutting edge through repeated use on ferrous and non-ferrous materials. It is sized for 5/16-24 threads, a UNF (Unified National Fine) pitch used widely in precision mechanical assemblies, hydraulic fittings, and instrumentation hardware. Licensed mechanics, maintenance technicians, and plumbing or HVAC service professionals keep rethreading dies on hand for field repairs where replacing a threaded fastener or nipple is impractical.

This die is suited for shop and field use wherever a 5/16-24 UNF external thread needs to be chased or restored. Common applications include cleaning thread damage on bolts, studs, and threaded rods in HVAC equipment, plumbing rough-in, and light industrial machinery. The right-hand thread direction matches standard UNF fastener conventions, making it a direct-fit tool for the vast majority of 5/16-24 threaded components encountered in trade service work.

Key Features

• High-speed steel construction retains cutting edge through repeated use on hard and soft metals
• 5/16-24 UNF thread size covers a common pitch in precision mechanical and HVAC hardware applications
• Right-hand thread direction matches standard UNF fastener convention
• Hex body allows direct engagement with a standard wrench or die stock handle for controlled torque application
• Single-piece construction with no moving parts for reliable, consistent thread restoration

Compatibility

Designed for rethreading and chasing 5/16-24 UNF right-hand external threads on bolts, studs, and threaded fittings across general mechanical, HVAC, and plumbing service applications.

Installation Notes

Rethreading dies are installed by qualified mechanics or service technicians using a die stock or wrench sized to the hex body. Before chasing threads on an assembled component, de-energize or shut off any system the fastener or fitting is part of to prevent injury. Apply cutting oil to the die and work surface to reduce heat and extend tool life. Follow applicable shop safety practices and inspect threads after chasing to confirm restore quality before reassembly.
