4307 3/8-16" High Carbon Steel Fractional Plug Tap - Vermont American

The Vermont American 4307 3/8-16" High Carbon Steel Fractional Plug Tap (Model 20022) is engineered for professional technicians and mechanics requiring precise internal thread cutting. This robust tap is designed to create right-hand threads efficiently and reliably in a variety of materials encountered in automotive and industrial environments.

Key Features

• High Carbon Steel Construction: Manufactured from high carbon steel for enhanced durability and resistance to wear during demanding threading operations.
• 3/8-16" Fractional Thread Size: Specifically designed for cutting standard 3/8-16" right-hand internal threads.
• Four-Flute Design: Promotes rapid and efficient chip clearance, reducing clogging and ensuring smoother tapping.
• Chamfered Leads: Features 3 to 5 chamfered threads, making it suitable for general-purpose applications where tapping to the very bottom of a blind hole is not a critical requirement.
• Etched Drill Size: The recommended drill size for pre-tapping is permanently etched onto the tool, providing quick and convenient reference on the job site.

Applications

This plug tap is an essential tool for creating new internal threads or cleaning out existing ones in various metal components. It is commonly used in automotive repair for tasks such as installing new fasteners or repairing stripped threads, and in industrial settings for general maintenance, fabrication, and assembly. Its design is particularly effective for through-holes or situations where the full depth of a blind hole does not need to be threaded.
