Features and Benefits
NPT (National Pipe Taper) refers to American National Standard Taper Pipe Threads. They are commonly used for general purpose applications and require a sealant.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
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.
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
