Hexagonal Slotted Nuts, also known as castle nuts, are a type of hex nut with a slot cut into two opposite sides. This slot is used for securing the nut in place with a cotter pin or a similar device, especially when used with a bolt in applications where vibration might cause loosening.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

Vibration Resistance: The slot allows for a cotter pin to be inserted, providing an additional level of security against loosening due to vibration.Aesthetics: The slot is less visible than other securing methods, making it more aesthetically pleasing in applications where appearance is important.Reusability: The slot allows for easy removal and reinstallation of the nut without damaging the threads.Easy Tightening: The slot provides a place for a screwdriver to engage, allowing for easy tightening even in tight spaces.

Scope of Application

Automotive and Machinery: Commonly used in the automotive industry for wheel assemblies and in machinery where frequent adjustments are required.Construction: Used in structural applications such as scaffolding and ladders where vibration or movement could cause other types of nuts to loosen.Aerospace: Employed in applications where a high level of security against loosening is required due to the nature of the environment.
