Century Drill and Tool 95002 4-40 NC Plug Tap

The Century Drill and Tool 95002 is a 4-40 NC (National Coarse) plug tap designed for cutting internal threads in pre-drilled holes. This standard plug tap features a tapered lead of 3-5 threads, making it the most versatile tap style for both hand and machine threading applications.

Key Features:

• Thread size: 4-40 NC (National Coarse thread specification)
• Plug tap design with gradual taper for easier starting and alignment
• Suitable for through holes and blind holes with adequate depth
• Compatible with standard tap handles and machine tap holders
• Carbon steel construction for durability

The 4-40 thread size is commonly used in electronics, small machinery, and precision equipment assembly. The plug tap style provides a good balance between the starting ease of a taper tap and the bottoming capability needed for most general-purpose threading operations.
