DIN1805 Stainless Steel Slotted Round Nut For Hook Spanner

Descrição

A slotted round nut is a type of nut with a circular shape and a series of slots cut into its outer circumference. These slots are designed to accommodate a cotter pin or a similar locking device, which can be inserted through the slots and a hole in the bolt or stud to prevent the nut from loosening due to vibration or other external forces. This makes the slotted round nut a reliable choice for applications where maintaining a secure connection is crucial.

Materials

Steel : This is one of the most common materials for slotted round nuts. Steel nuts offer high strength and durability, and they can be further classified into carbon steel and alloy steel. Carbon steel nuts are cost – effective and suitable for general – purpose applications, while alloy steel nuts have enhanced properties such as better corrosion resistance and higher tensile strength, making them suitable for more demanding environments.

Stainless Steel : Stainless steel slotted round nuts are known for their excellent corrosion resistance. They are often used in applications where the nut will be exposed to moisture, chemicals, or harsh weather conditions, such as in marine, food processing, and chemical industries.

Brass : Brass nuts are aesthetically pleasing and have good electrical conductivity. They are also relatively corrosion – resistant, which makes them suitable for applications in the electrical and plumbing industries.

Surface Treatment

Zinc Plating : Zinc plating is a common surface treatment for steel slotted round nuts. It provides a layer of protection against corrosion, and the zinc coating can be further passivated to enhance its anti – corrosion properties.
Chrome Plating : Chrome – plated nuts have a shiny and decorative appearance in addition to corrosion resistance. They are often used in applications where both functionality and aesthetics are important, such as in automotive and furniture industries.

Black Oxide Coating : This treatment gives the nut a black finish and provides some corrosion resistance. It is also commonly used for its aesthetic appeal and is often found in applications where a more discreet or industrial look is desired.

Specific Specifications

Size : Slotted round nuts come in a wide range of sizes, typically specified by the diameter of the bolt or stud they are intended to fit. Common sizes range from M3 (for metric nuts) or #0 – 80 (for imperial nuts) to larger sizes like M24 or 1 – 1/2 inches.
Number of Slots : The number of slots on a slotted round nut can vary. Commonly, there are 6, 8, or 12 slots, which are evenly spaced around the outer circumference of the nut.

Thread Type : They can have metric or imperial threads. Metric threads are specified by the pitch (the distance between adjacent threads), while imperial threads are specified by the number of threads per inch.
Application Areas

Automotive Industry : Slotted round nuts are used in various automotive components, such as suspension systems, steering linkages, and engine parts. In these applications, the nuts need to stay securely fastened to prevent any loosening that could lead to mechanical failures and safety hazards.

Aerospace Industry : Due to the high – reliability requirements in aerospace, slotted round nuts are used in critical aircraft components, including landing gear assemblies, control surfaces, and engine mounts. The locking mechanism provided by the slots and cotter pins ensures the integrity of the connections under extreme conditions.

Machinery and Equipment : In industrial machinery, slotted round nuts are used to secure shafts, gears, and other moving parts. They help maintain the proper alignment and function of the equipment, reducing the risk of breakdowns and downtime.

Excellent Cases

Automotive Suspension Systems : In a high – performance sports car, slotted round nuts are used to secure the suspension components. The continuous vibrations and forces experienced during high – speed driving could cause ordinary nuts to loosen over time. However, the slotted round nuts with cotter pins prevent this from happening, ensuring the stability and safety of the vehicle’s handling.

Aircraft Landing Gear : On commercial airliners, slotted round nuts are used in the landing gear assemblies. These nuts are subjected to extreme forces during takeoff, landing, and taxiing. The locking feature of the slotted round nuts ensures that the landing gear remains securely attached to the aircraft, which is crucial for the safety of passengers and crew.
