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.
Stainless steel is a strong, corrosion-resistant alloy with excellent resistance to heat. It is used in high-stress, outdoor and corrosive applications.
UNC indicates unified national coarse thread standards. Coarse threads have more TPI (threads per inch) and larger thread pitches.
