Grade 8.8 Hexagon Slotted Nut/ Castle Nut with Black


Grade 8.8 Hexagon Slotted Nut/ Castle Nut with Black
Product Description

High Precision 8.8 Hexagon Slotted Carbon Steel Black Castle Nut for Mounting Radiator
    A castellated nut, also known as a castle nut or slotted nut, is a type of fastener 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 typically used in applications where a secure and reliable locking mechanism is required. They are often paired with a bolt or axle that has a hole drilled through its threaded end. Once the nut is properly tightened, it is rotated until the slot aligns with the hole, and then secured using a split pin, R-clip, or safety wire. This makes it an effective positive locking device, especially in low-torque environments such as securing wheel bearings.
