**Product Description:**
**Color Zinc Plated Cage Nut with Carbon Steel Material - Size M5**
A castellated nut, also known as a castle nut or slotted nut, is a type of nut that features notches or slots cut into one end. The name is derived from its resemblance to the crenellated parapet of a medieval castle. These nuts are commonly used in applications where a locking mechanism is required to prevent loosening due to vibration.
The nut is typically used with a bolt or axle that has one or two holes drilled through its threaded end. After tightening the nut to the proper torque, if the slot does not align with the hole in the fastener, the nut is rotated forward to the nearest slot. A split pin, R-clip, or safety wire is then inserted through the aligned hole and slot to secure the nut in place. This makes it a reliable locking device, especially in low-torque applications such as securing wheel bearings or other mechanical components.
