Irwin 7/16-20 NF HCS Re-threading Hexagon Fractional Die (7240)

The Irwin 7/16-20 NF HCS Re-threading Hexagon Fractional Die (7240) is a high-quality tool engineered for the precise task of repairing and cleaning up damaged external threads. Made from high carbon steel, this fractional die is specifically designed to restore threads on bolts and studs that have been stripped, rusted, or cross-threaded. Its unique hexagon shape allows it to be used with a standard wrench, socket, or hexagon die stock, offering exceptional versatility and access in confined or hard-to-reach areas. This makes it an indispensable tool for automotive repairs, maintenance, and various mechanical applications. The 7/16-20 NF thread size is a common standard, ensuring compatibility with a wide range of fasteners. Instead of replacing an entire bolt, this re-threading die provides a cost-effective and time-saving solution for extending the life of your hardware.

KEY FEATURES AND BENEFITS:

• Crafted from high carbon steel for superior durability and hardness
• Hexagon shape allows easy use with wrenches and sockets
• Ideal for tight or confined workspaces where round dies can't fit
• Restores threads by cleaning and reforming them—not cutting new ones
• Helps preserve the original fastener’s integrity
• Cost-effective alternative to replacing damaged bolts or studs

SPECIFICATIONS:

• Part Number: 7240
• Thread Size: 7/16-20 NF
• Material: High Carbon Steel (HCS)
• Thread Direction: Right-hand

HOW TO USE:

1. Preparation: Clean the damaged bolt or stud thoroughly with a wire brush to remove any dirt, rust, or debris. This helps the die to engage the threads properly.
2. Engagement: Place the re-threading die onto the end of the damaged thread. Ensure the die is aligned straight with the bolt to prevent further damage. The hexagon shape allows you to use a wrench or socket to turn it.
3. Threading: Apply steady, even pressure while turning the die clockwise (for right-hand threads). Turn the die a quarter turn, then back it off slightly to break any chips or debris.
4. Completion: Continue this process until the die has passed completely over the damaged section of the thread. Remove the die and inspect the repaired thread for a smooth, clean finish.
