Irwin 5-Piece SAE Coarse Thread Chaser (3094100)

The Irwin 5-Piece SAE Coarse Thread Chaser (3094100) is a specialized tool set designed to repair and clean damaged threads on studs and fasteners. Unlike a tap or die that cuts new threads, this set is built to restore existing threads that have been cross-threaded, rusted, or covered in debris. The chasers feature a unique deep-well design that allows them to run the full length of a stud, even in recessed or hard-to-reach areas. Made from high-carbon steel, these tools are built to last and provide a reliable way to save and reuse hardware. The included sizes cover the most common coarse SAE threads, making this set an essential addition to any mechanic's or DIYer's toolkit.

KEY FEATURES AND BENEFITS:

• Thread Repair Functionality: Specifically engineered to clean and repair damaged coarse threads without removing material, preserving the original strength and integrity of the fastener. This prevents the risk of over-cutting or weakening threads, which can happen when using a tap or die for repair.
• Deep Well Design: The chasers are designed with a 1-3/4" deep capacity, allowing them to fully cover and repair threads on longer studs or those located in deep wells, such as axle studs. This ensures a complete and thorough repair along the entire thread length.
• Versatile Tool Compatibility: Each chaser has a low-profile hexagonal head, which can be turned using a standard socket, an open-ended wrench, or even Vise-Grip pliers. This versatility means you can use the set with tools you likely already have, making it a convenient and practical solution.
• High-Carbon Steel Construction: The tools are made from high-carbon steel, providing exceptional strength and a longer lifespan. This material choice ensures the chasers can withstand the demands of frequent use while effectively restoring threads.
• Comprehensive Set: The set includes five of the most common coarse SAE thread sizes, providing a ready solution for a wide range of automotive and mechanical repair tasks.

HOW TO USE:

1. Identify the correct size: Select the thread chaser that matches the size of the damaged stud or bolt. Ensure you're using the coarse thread chaser for coarse threads.
2. Align the chaser: Position the chaser on the stud or bolt. You can thread it backward initially to use the internal teeth as a guide, ensuring proper alignment with the existing threads.
3. Turn and clean: Once aligned, use a socket, wrench, or Vise-Grip pliers to slowly turn the chaser clockwise. Work it down the length of the thread, allowing it to clean and reshape the damaged areas.
4. Remove and inspect: After running the chaser down the entire length of the thread, unscrew it and inspect the stud or bolt. The threads should be clean and restored to their original profile.
5. Clean up: Remove any metal shavings or debris that were dislodged during the repair process.
