Irwin 1/4″-28 NF HCS 1″ Flat Hexagon Fractional Die (6523ZR)

Description

The Irwin 1/4″-28 NF HCS 1″ Flat Hexagon Fractional Die (6523ZR) is a high-quality tool engineered for creating and repairing external threads. Made from high-carbon steel (HCS), this die is designed for durability and precision, providing a clean cut on a variety of materials. Its hexagonal shape is a key feature, allowing it to be used with a standard wrench or socket, which is especially useful when working in spaces where a traditional round die stock won’t fit. The National Fine (NF) thread type is common in applications that require a secure, vibration-resistant connection, making this die an essential tool for automotive, machinery, and general repair tasks. Whether you’re rethreading a damaged bolt or cutting new threads, this tool offers a reliable and efficient solution for professional and personal use.

KEY FEATURES AND BENEFITS:

• High-carbon steel construction: Offers strength, durability, and a long service life.
• 1/4″-28 NF thread size: Suitable for fine thread applications requiring a secure fit.
• 1″ flat hexagon design: Allows use with a standard wrench or socket in tight spaces.
• Compact profile: Provides better access compared to round dies in constrained areas.
• Right-hand threading: Compatible with most common mechanical applications.

SPECIFICATIONS:

• Thread Size: 1/4″-28 NF
• Hexagon Size: 1″ (across the flats)
• Material: High Carbon Steel (HCS)
• Thread Direction: Right Hand

HOW TO USE:

1. Prepare the Workpiece: Ensure the bolt, stud, or rod is clean and the end is chamfered. This helps the die start straight. Secure the workpiece in a vise.
2. Mount the Die: Place the die onto the end of the workpiece. You can use a die stock designed for hexagon dies or a wrench/socket that fits the 1″ hex.
3. Start the Cut: Apply light, even pressure while turning the die clockwise. This starts the initial cut. Make sure the die is entering the workpiece straight to prevent cross-threading.
4. Cut the Threads: Continue turning the die, periodically reversing it a quarter or half turn. This breaks the metal chips, prevents clogging, and ensures a clean thread.
5. Lubricate: Use a cutting fluid or lubricant during the threading process to reduce friction, extend the life of the die, and achieve a smoother finish.
6. Complete the Process: Once the desired thread length is achieved, turn the die counter-clockwise to remove it from the workpiece.
