LH Fractional Plug Tap - 5/16 In - 24NF - Hanson

The Hanson 2129 LH Fractional Plug Tap is engineered for precision and durability in professional automotive and industrial applications. This specialized tool is designed to cut crisp, accurate 5/16"-24 NF left-hand threads, essential for specific fastening requirements where standard right-hand threads are unsuitable or could dangerously loosen during operation.

Key Features

• HSS Ground Thread Construction: Manufactured from High-Speed Steel with precision ground threads for superior cutting performance and extended tool life.
• Left-Hand Rotation: Specifically designed to cut left-hand threads, critical for specialized fasteners and components that require counter-clockwise tightening.
• Plug Tap Style: The plug tap configuration features 3-5 chamfered threads, making it suitable for through holes and in situations where slight starting engagement is desired.
• Four Flute Design: Optimized four-flute geometry efficiently clears chips, reducing clogging and ensuring smooth, consistent thread cutting.
• H3 Pitch Diameter Limits: Adheres to H3 pitch diameter limits, ensuring the precise thread fit required for professional-grade assemblies.

Applications

This left-hand tap is indispensable for mechanics and industrial technicians working with machinery where reverse rotation or specific torque applications necessitate left-hand threaded fasteners. Common uses include repairing or creating threads for grinding wheel retaining nuts, certain automotive spindle nuts, bicycle pedals, and various industrial components designed to prevent loosening under counter-rotational forces. It is a critical tool for maintaining the integrity and safety of specialized equipment.
