Value Collection JY4843223 Hand Tap 7/16-27 Uns Plug Hss

Product Description

The VALUE COLLECTION JY4843223 is a 7/16-27 UNS straight flute hand tap designed for cutting internal threads by hand in a variety of materials. Built from high speed steel with a bright uncoated finish, this tap offers solid wear resistance for general-purpose threading applications. The plug chamfer style — with a moderate lead — makes it suitable for through-holes and deeper blind holes where a starting taper is not needed. It carries a Class 3B fit and an H3 thread limit, producing threads with tight tolerances appropriate for precision fastener applications. Overall length is 3-5/32 inches. Licensed trades and machining professionals use this tap for maintenance, repair, and fabrication work.

This tap is suited for threading 7/16-27 UNS holes in ferrous and non-ferrous metals, plastics, and similar materials. The 4-flute straight flute geometry handles chip evacuation effectively in through-hole operations and in shorter blind holes. Right-hand thread direction matches standard fastener conventions. It is commonly used in maintenance and repair operations, light manufacturing, and field service environments where hand tapping is required.

Key Features

• 7/16-27 UNS thread size with right-hand thread direction
• Plug chamfer provides a moderate lead for through-holes and deeper blind holes
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish — no coating concerns for applications where coatings are undesirable
• H3 thread limit and Class 3B fit for tight-tolerance threading
• 4-flute straight flute design for effective chip evacuation in standard threading conditions

Compatibility

Designed as a standard hand tap for 7/16-27 UNS threaded hole applications in maintenance, repair, and fabrication operations where a plug chamfer and Class 3B fit are specified.

Installation Notes

Use this tap with a properly sized tap wrench and apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread quality. Ensure the tap is started square to the hole to avoid thread misalignment or tap breakage. Back the tap off periodically to break and clear chips, especially in deeper holes. Follow applicable shop safety practices when hand tapping.
