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 design is inspired by the crenellations found on medieval castle walls, giving it its distinctive appearance. These nuts are commonly used in applications where a secure and reliable connection is essential. They are typically paired with a bolt that has a hole drilled through its threaded end. Once the nut is tightened to the correct torque, it is rotated until the slot aligns with the hole. A cotter pin, R-clip, or safety wire is then inserted through the hole to lock the nut in place, preventing loosening due to vibration or movement.
