Features and Benefits
Thumb nuts are used in light-duty applications that do not require extremely tight fasteners. They are easily tightened by hand.
Round knurled head types have thick, cylindrical heads with a pattern of ridges that allow for easy gripping and tightening by hand.
Brass is an alloy of copper and zinc that is durable, nonmagnetic and conductive.
UNC indicates unified national coarse thread standards. Coarse threads have more TPI (threads per inch) and larger thread pitches.
