1.Product Description

A castle nut, also called a castle nut or slotted nut, is a nut with slots (notches) cut into one end.The name comes from the nut's resemblance to the crenellated parapet of a medieval castle.

The bolt or axle has one or two holes drilled through its threaded end. The nut is torqued properly and then, if the slot is not aligned with the hole in the fastener, the nut is rotated forward to the nearest slot. The nut is then secured with a split pin, R-clip or safety wire. It is a positive locking device.

Castellated nuts are used in low-torque applications, such as holding a wheel bearing in place.

Castle nut is fastened by a screw through the front and rear axles front and rear axle of the vehicle is fixed, so that the frame and tires together, in order to prevent the nut loose, must be fixed with a cotter pin through the slotted nut groove, and the opening to secure the pin slotted nut must pass through from the middle of the screw shaft, generally requires two screw shaft drilling, hole diameter and slotted nut width and groove depth determines the choice of what size cotter pins, elected by the axle cotter pin and slotted screws and nuts are more match time, through the axle nut to secure the front wheel and the frame screw, a cotter pin through axle screw fastener holes live slotted nut, slotted nut is not so produce loose, so that the vehicle is not in motion when the loose.

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
