Detail & Specs
Acorn nuts are used to cover and protect exposed threads. The flange acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.
The serrated flange bottom style provides a locking action, digging into the parent material when tightened down and able to withstand extreme vibrations without loosening. Serrated flange nuts are meant to permanently mar the material they are installed against.
The smooth flange bottom style is non-locking and will not damage the threads of bolts or screws and can be reused.
Common applications: motorcycles, industrial machinery, plumbing, machine construction, biogas, finish work.
Zinc Plated and Yellow Zinc Plated finishes provide corrosion resistance without sacrificing strength.
Also known as dome nut, hexagon domed cap nut with integrated washer
