A HEXAGHEXAGON Slotted Nut is a mechanical fastener that has a hexagonal shape. They are commonly used for many fastening applications. They are ISO 7035 standard and can be used for a wide variety of applications.
A hex slotted nut is hexagonal in shape with slots milled into the top that allow a split pin or cotter pin to be inserted into the nut. Hex slotted nuts range in diameter from one-fourth to one-half inch. They are also available in heavy, or thick, types with a longer engagement length.
