Westward 7/16"-14 UNC Bottoming Tap
This Westward straight flute hand tap cuts internal threads in a 7/16"-14 UNC size. It is designed for general-purpose threading tasks in maintenance and repair workshops. The bottoming chamfer allows threading close to the bottom of blind holes. Four flutes provide balanced chip clearance during hand operation.
High-Speed Steel Construction and Bright Finish
The tap is manufactured from high-speed steel for durability when cutting ferrous and non-ferrous materials. A bright, uncoated surface resists galling on softer metals and is easy to inspect for wear. Right-hand cutting direction matches standard fastener threads. The H5 thread limit produces a Class 2B fit for standard commercial tolerances.
Verify Hole Size and Thread Depth Before Use
Check that your drilled hole matches the required tap drill diameter for 7/16"-14 UNC threads. Ensure the workpiece thickness accommodates the 1.44 inch thread length and 3.16 inch overall length. This tool is not suited for machine tapping or high-volume production runs.
