Irwin Hanson Machine Screw Plug Tap

The Irwin Hanson Machine Screw Plug Tap line is made for cutting internal threads in drilled holes. It is also called a machine screw thread tap or hand tap. Plug taps have a moderate chamfer on the lead end. That chamfer makes them easy to start and lets them cut threads cleanly in through holes and in blind holes with enough depth.

Key Features:

• Plug chamfer design that starts easily and is suited to general-purpose tapping
• Made from high-speed steel or high carbon steel, depending on the model, for durable cutting edges
• Cuts standard National Coarse (NC) machine screw threads
• Ground thread form for consistent, accurate threads
• Suited to hand tapping with a tap wrench, and to shop, maintenance and repair work

Irwin Hanson is a long-established name in hand threading tools. These taps give dependable thread quality for fabrication, repair and general workshop use. Use cutting oil and the correct tap drill size for the best results and longer tool life.
