DIN 11024
DIN 11024 is a standard from the German Institute for Standardization (DIN) for cotter pins, also known as safety pins or hairpin cotters. This standard defines the dimensions, tolerances, and mechanical properties of cotter pins used for securing bolts and pins in various mechanical and structural applications. Cotter pins according to DIN 11024 are available in different sizes and materials to meet a wide range of requirements.
Features and Dimensions:
DIN 11024 cotter pins are available in various diameters and lengths, with common sizes ranging from 1 mm to 8 mm in diameter and up to 100 mm in length. These pins have a double-leg, hairpin-like shape, making them easy to insert and remove while providing reliable securing.
Materials and Surface Treatments:
DIN 11024 cotter pins are manufactured from various materials to meet different strength and corrosion-resistance requirements. Common materials include:
-
Spring steel
-
Stainless steel
-
Brass
They can also be provided with surface treatments like galvanizing or nickel plating to improve corrosion resistance.
Areas of Application:
DIN 11024 cotter pins are used in many fields, including:
-
Mechanical engineering: For securing bolts and studs in machines and equipment.
-
Automotive industry: For securing connections in vehicles.
-
Agricultural machinery: For securing components in farming equipment.
-
Construction: For securing structural connections in building structures.
Assembly and Use:
When installing DIN 11024 cotter pins, it’s important to select the correct size and suitable material to ensure optimal performance and durability of the connection. The pin should be pushed through the hole in the bolt or stud and then splayed to ensure a secure connection.
Conclusion:
DIN 11024 cotter pins are essential fastening elements in many mechanical and structural applications. Their standardized dimensions and materials ensure reliable and safe securing of connections to meet the demands of various fields.
