LH Fractional Plug Tap - 3/4 In -16 NF - Hanson

The Hanson 2160 LH Fractional Plug Tap is engineered for professional technicians and mechanics requiring precise left-hand threading capabilities. This high-speed steel (HSS) ground thread tap is designed for durability and accuracy in demanding automotive and industrial environments, allowing for the creation or repair of specialized left-hand threads. Its robust construction ensures consistent performance and a clean thread finish for critical applications.

Key Features

• HSS Ground Thread Construction: Manufactured from high-speed steel with precision-ground threads for superior strength, extended tool life, and clean cutting action.
• Left-Hand Threading: Specifically designed to cut threads with a left-hand rotation, essential for applications where conventional right-hand threads are unsuitable or would loosen during operation.
• 3/4"-16 NF Size: Provides a common fractional size, 3/4 inch with 16 National Fine threads per inch, suitable for a range of professional fastening and repair tasks.
• Four Flutes: Features four flutes for efficient chip evacuation, reducing loading and improving thread quality, particularly in deeper holes.
• H3 Pitch Diameter Limits: Designed to H3 pitch diameter limits, ensuring a controlled thread fit for reliable fastening without excessive play or binding.
• Plug Tap Design: The plug tap configuration has a chamfer of 3-5 threads, making it versatile for through-hole applications and starting new threads.

Applications

This left-hand tap is indispensable for applications requiring the creation or repair of reverse threads. Common uses include repairing damaged threads on automotive components such as certain axle nuts, fan clutches, or specific steering linkages where left-hand fasteners prevent loosening under operational forces. It is also widely used in industrial machinery for specialized assembly, maintenance, and fabrication projects where components must resist rotation in a clockwise direction.
