Features and Benefits
Plug chamfers are the most commonly used chamfer and designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Hand taps are used to cut threads in blind or through holes. They are used by hand or in general purpose machine operations.
Carbon steel is a soft, durable metal. It is commonly used for general purpose applications on abrasive materials, nonferrous materials, plastics and wood.
Oxide, also known as black oxide or steam oxide, is a surface treatment that prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and ferrous metals.
