Value Collection JY63328538 Hand Tap 7/16-20 Unf 4 Flute

Product Description

The VALUE COLLECTION JY63328538 is a 7/16-20 UNF plug chamfer hand tap designed for cutting internal threads in through-holes and blind holes where full thread engagement is required near the bottom. Manufactured from high-speed steel with a bright finish, this tap delivers reliable thread-cutting performance across a range of ferrous and non-ferrous materials. The H3 thread limit holds tight tolerances suitable for standard UNF fastener fits. With a 6-inch overall length and 4 right-hand flutes, it is sized for use with standard tap wrenches in manual threading operations performed by machinists, maintenance mechanics, and tool-and-die professionals.

This tap is suited for manual threading applications in repair, fabrication, and production environments. The plug chamfer style features a 3-to-5 thread lead-in, making it the standard choice for most general-purpose hand tapping where the hole has sufficient depth to accept the chamfer. It works in steel, cast iron, aluminum, brass, and similar machinable materials. Typical applications include threading bolt holes in equipment frames, brackets, pulleys, and mechanical assemblies requiring 7/16-20 UNF fastener engagement.

Key Features

• 7/16-20 UNF thread form for fine-pitch internal threading
• Plug chamfer with 3-to-5 thread lead-in for general-purpose hand tapping
• High-speed steel construction for durability across common machinable materials
• H3 thread limit for consistent tolerance control on standard UNF fits
• 4 right-hand flutes for efficient chip evacuation during manual tapping
• Bright finish suitable for use with standard cutting fluids and tapping compounds

Compatibility

Designed as a standard replacement or general-use hand tap for manual threading operations requiring 7/16-20 UNF internal threads in through-hole and blind-hole applications.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a standard tap wrench. Ensure the workpiece is secured and the tap is started perpendicular to the hole surface to prevent thread misalignment or tap breakage. Apply appropriate cutting fluid or tapping compound for the workpiece material before and during tapping. Power down any associated machinery and secure the workpiece fully before beginning manual threading operations.
