Specification Brand : RAW PRODUCTS CORP BulletPoint1 : Castle nuts are used in conjunction with a cotter pin to prevent loosening. BulletPoint2 : This nut has slots (notches) cut into one end. The name comes from the nut’s resemblance to the crenellated parapet of a medieval castle. BulletPoint3 : The bolt or axle has one or two holes drilled through its threaded end. BulletPoint4 : The nut is torqued properly and then, if the slot isn't aligned with the hole in the fastener, the nut is rotated to the nearest slot. The nut is then secured with a cotter pin or safety wire. BulletPoint5 : Castellated nuts are used in low-torque applications, such as holding a wheel bearing in place.
