DIN1481 Elastic Cylindrical Pins

DIN 1481 elastic cylindrical pins are specialized fasteners used in automotive and industrial applications to align, locate, or secure components. These pins are hollow, cylindrical, and designed to compress during installation, expanding to fill the hole and create a tight friction fit. The elasticity of these pins allows them to absorb shocks, resist vibrations, and maintain a secure connection even in dynamic environments.
DIN 1481 pins are made from coiled or rolled metal strips that compress during installation and expand to fill the hole. This flexibility ensures a snug fit and helps absorb shocks and vibrations, making them ideal for high-stress automotive applications.
The inherent elasticity of these pins helps them resist loosening due to vibrations, making them suitable for high-vibration environments such as suspension systems, steering linkages, and engine mounts.
Common materials include carbon steel , stainless steel , and sometimes aluminum . Stainless steel is often used in corrosive environments, while carbon steel provides higher strength for heavy-duty applications.
