Description
The Irwin 10-24 NC Bottom Bulk HCS Machine Screw Tap (1228) is a high-quality threading tool crafted to meet the demands of professional and DIY projects. This tap is specifically engineered to create internal 10-24 National Coarse threads, making it an essential component for maintenance, repair, and fabrication work. Made from high-carbon steel, it provides a balance of toughness and wear resistance, ensuring it stands up to repeated use. The tap’s design is optimized for hand threading applications, allowing for controlled and precise thread formation in various materials. It is a reliable choice for creating new threads or cleaning out existing ones, and its right-hand cutting direction ensures smooth operation.
KEY FEATURES AND BENEFITS:
- Precision Threading: The tap is designed to create accurate and clean 10-24 NC threads, which are commonly used in machine screw applications, ensuring a proper fit for fasteners.
- Bottoming Design: The bottoming tap style has a short chamfer, allowing you to create threads close to the bottom of a blind hole. This is crucial for applications where the full depth of the hole needs to be threaded.
- Durable Construction: Made from high-carbon steel (HCS), this tap provides excellent durability and edge retention, extending the life of the tool and offering consistent performance.
- Efficient Chip Removal: The 4-flute design facilitates rapid and efficient chip removal, preventing material buildup and reducing the risk of tap breakage, which results in a cleaner and faster threading process.
- Versatile Application: This tap is suitable for a wide range of materials and is perfect for creating new threads or rethreading damaged ones in various maintenance and repair scenarios.

HOW TO USE:
- Prepare the Hole: First, drill a pilot hole using the appropriate drill bit size for a 10-24 NC thread. It is crucial that the hole is straight and clean of debris.
- Align the Tap: Insert the tap into a tap wrench, ensuring it is held firmly and straight. Align the tap with the center of the pre-drilled hole.
- Start Threading: Apply light, even pressure and slowly rotate the tap wrench clockwise to begin cutting the threads.
- Clear Chips: After every one to two full rotations, turn the tap wrench a half-turn counter-clockwise. This action breaks the metal chips, preventing them from clogging the flutes and making the process smoother.
- Complete the Thread: Continue the forward and reverse motion, gradually advancing the tap until you have reached the desired depth. Be careful not to apply excessive force, which could cause the tap to break.
- Remove the Tap: Once the threading is complete, carefully rotate the tap wrench counter-clockwise to back the tap out of the newly created threads.
