1 Hexagonal nut most widely used.
C grade nuts for rough surface on the machinery, equipment or structures on less precision;
Class A (for nominal thread diameter D≤16 mm) and Level B (applicable to nominal thread diameter D> 16 mm) nut for surface is smooth, the high precision of machines, equipment or structures.
Type 2 hexagon nuts of the thicker, more often it needs for assembly and disassembly of the occasion. The thickness of the thin hexagonal nut, used to be connected to parts of the surface of the space-constrained applications, also used for primary prevention of back nut loosen lock nut.
Hexagon slotted nut and the screw terminal designed for bolt holes used in conjunction in order to insert the cotter pin from the nut of the screw holes in the slot to prevent the automatic return pine nuts, mainly for having a vibration load or alternating load occasions
