LH Fractional Plug Tap - 7/16 In - 20 NF - Hanson

The Hanson 2140 LH Fractional Plug Tap is engineered for professional technicians and mechanics requiring precise left-hand threading. This high-speed steel (HSS) tap is designed to create internal threads with a left-hand rotation, essential for specific automotive and industrial applications where conventional right-hand threads would loosen under operational forces. Its durable construction ensures reliable performance in demanding workshop environments.

Key Features

• Left-Hand Threading: Specifically designed to cut 7/16" - 20 NF threads with a left-hand rotation.
• High-Speed Steel (HSS): Constructed from HSS for superior hardness, wear resistance, and extended tool life.
• Ground Thread: Precision-ground threads ensure accurate and consistent thread formation.
• Plug Tap Design: Features a plug chamfer, ideal for through-hole applications, providing a balance of easy starting and full thread cutting.
• Four Flutes: Optimizes chip evacuation during the tapping process, reducing clogging and improving thread quality.
• H3 Pitch Diameter Limits: Guarantees precise thread dimensions for a secure and compatible fit.

Applications

This left-hand fractional plug tap is indispensable for creating or repairing threads on components that utilize left-hand fasteners. Common applications include specific machinery parts, pumps, automotive assemblies where reversed threads prevent loosening due to rotation, and various industrial equipment. Professional technicians will find it essential for tasks involving left-hand threaded studs, bolts, or shafts where precise and durable thread repair or creation is critical.
