Irwin 3/8"-16 NC HCS Re-threading Hexagon Fractional Die (7234)

The Irwin 3/8"-16 NC HCS Re-threading Hexagon Fractional Die (7234) is a specialized tool designed to restore and repair damaged external threads on bolts and studs. Made from high carbon steel, this fractional die is engineered for durability and precision, allowing you to fix worn or stripped threads without the need for a traditional die stock. Its unique hexagon shape enables it to be used with a standard wrench or socket, providing superior versatility and access in tight or confined spaces where a conventional die stock might not fit. This makes it an essential tool for automotive repair, machinery maintenance, and various industrial applications where thread integrity is critical. The Irwin 7234 saves you the time and cost of replacing damaged hardware, offering a reliable and efficient solution for thread repair.

KEY FEATURES AND BENEFITS:

• Thread Restoration: Specifically engineered to clean and repair damaged threads, restoring them to their original condition and ensuring a proper, secure fit. This eliminates the need to replace expensive bolts and studs, saving you time and money.
• High Carbon Steel Construction: The die is made from high carbon steel (HCS), providing excellent hardness and wear resistance. This material ensures a long tool life and reliable performance, even when working on tough materials.
• Hexagon Design: The hexagon shape allows the die to be turned with a standard wrench or socket. This feature offers increased flexibility and makes it easy to work in spaces where a bulky die stock would be impractical, providing greater access and control.
• Right-Hand Threading: Designed for right-hand threads, which are the most common type used in fasteners, ensuring compatibility with a wide range of standard bolts and studs.
• Precise Sizing: The die is precisely sized for 3/8"-16 NC threads, providing an accurate and clean repair. This ensures that the restored threads will function correctly with corresponding nuts and tapped holes.

SPECIFICATIONS:

• Thread Size: 3/8"
• Threads Per Inch (TPI): 16
• Thread Standard: NC (National Coarse)
• Material: High Carbon Steel (HCS)
• Outside Diameter / Hexagon Width: 25/32"
• Thickness: 3/8"
• Cutting Direction: Right-hand
• Number of Flutes: 3

HOW TO USE:

1. Clean the Bolt/Stud: Before beginning, thoroughly clean the damaged thread with a wire brush to remove any dirt, rust, or debris. This ensures the die can engage the threads properly.
2. Lubricate: Apply a cutting oil or lubricant to the damaged thread and the die itself. This reduces friction, prevents overheating, and extends the life of the tool.
3. Engage the Die: Place the die squarely on the end of the damaged thread. Ensure the die is aligned straight with the bolt to prevent cross-threading.
4. Begin Turning: Use a wrench or socket on the hexagon-shaped die and begin turning it clockwise. Apply firm, steady pressure, and turn it slowly to start.
5. Back and Forth Motion: After a couple of turns, turn the die counter-clockwise a quarter turn to break the chip. Repeat this back-and-forth motion (two turns forward, a quarter turn back) as you work your way down the entire length of the damaged thread.
6. Remove and Inspect: Once you have run the die all the way down the thread, remove it and clean the newly restored threads. Inspect them to ensure they are smooth and functional.

BENEFITS OF USING IRWIN 3/8"-16 NC HCS RE-THREADING HEXAGON FRACTIONAL DIE (7234):

• Cost-Effective Repair: This tool allows you to fix damaged fasteners instead of buying new ones, saving you money on replacement parts.
• Enhanced Accessibility: The hexagon design makes it easy to use in hard-to-reach areas, which is a significant advantage over traditional die stocks.
• Extended Tool Life: Made from high carbon steel, this die resists wear and tear, providing long-lasting performance for many repair jobs.
• Professional Results: It restores threads to a precise, factory-like condition, ensuring a perfect fit with nuts and other threaded components.
• Time-Saving Solution: Quickly and efficiently repairs threads, minimizing downtime on a project and getting your equipment back in working order faster.
• Reduced Risk of Injury: Using a wrench or socket to turn the die provides a secure grip and reduces the risk of slipping, making the repair process safer.

FEATURES:

• Designed for Repair: Specifically made for repairing and cleaning existing threads, not for cutting new ones.
• Right-Hand Cut: Optimized for repairing the most common type of thread direction.
• Compact Size: Its small form factor allows for use in confined spaces where larger tools cannot fit.
• Fractional Sizing: Clearly marked for 3/8"-16 NC threads, ensuring you have the right tool for the job.
