Tuercas tipo castillo

A castellated nut is a locking nut which, when used in conjunction with a cotter pin, can withstand a lot of vibration and movement due to its shape. Castellated nuts offer a really firm hold while remaining easy to remove. Because of their strength and locking ability, they are often used in places where there is a lot of vibration such as wheel spindles, holding bearings and wheels firmly in place despite constant movement. They can be made of various materials but are mostly steel or stainless steel.
