Features and Benefits
Check nuts are installed by hand over the first nut to prevent fasteners from loosening. They are used in high-vibration applications.
Round knurled head types have thick, cylindrical heads with a pattern of ridges that allow for easy gripping and tightening by hand.
Steel is strong and durable but less corrosion resistant than stainless steel. To improve its resistance to corrosion, it may receive additional finishes and coatings.
UNC indicates unified national coarse thread standards. Coarse threads have more TPI (threads per inch) and larger thread pitches.
