1/4"-32 NEF Bottom Tap - Hanson

The Hanson 1524 1/4"-32 NEF Bottom Tap is engineered for professional technicians and machinists who demand precise, full-depth threading in blind holes. This specialized tool maximizes usable thread length and fastener grip, ensuring reliable and secure performance in critical automotive and industrial applications.

Key Features

• Optimized Bottoming Geometry: Designed to cut full 1/4"-32 NEF threads close to the bottom of blind holes, ensuring maximum thread engagement and secure fastening for critical components.
• 1/4"-32 NEF Extra-Fine Pitch: Produces accurate National Extra Fine threads, crucial for applications requiring tight tolerances and fine adjustment, such as carburetor bodies, small engine parts, and precision instrumentation.
• High-Speed Steel Construction: Manufactured from High-Speed Steel (HSS), offering good wear resistance and edge retention for consistent results across various materials, including carbon steel, alloy steel, aluminum, brass, and other non-ferrous metals.
• Efficient Chip Evacuation: Features a bright finish and optimized flute geometry to reduce friction and promote clean chip flow, minimizing the risk of tap breakage in deep or tight blind hole applications.
• Professional-Grade Versatility: Suitable for integration into drill presses, milling machines, or for hand tapping with a proper tap wrench in professional automotive and industrial workshop environments.

Applications

The Hanson 1524 1/4"-32 NEF Bottom Tap is well-suited for critical threading tasks in blind holes on components such as sensor ports, fuel system fittings, small housings, and precision brackets. It is commonly utilized by automotive technicians, machinists, and maintenance crews for repair, rethreading, and light fabrication work where extra-fine pitch threads are specified. This tap is ideal for tasks within automotive systems, aerospace assemblies, and general industrial equipment requiring secure fastener engagement in limited-depth holes.
