ANSI/ASME B18.8.2 Coiled Spring Pins

ANSI/ASME B18.8.2 coiled spring pins are designed to compress during installation and expand to fill the hole, creating a tight friction fit that secures components in place. They are widely used in automotive applications where vibration resistance, ease of installation, and flexibility are critical. The ANSI/ASME B18.8.2 standard specifies the dimensions, materials, and performance requirements for these pins, ensuring consistency and reliability across various applications.
Coiled spring pins consist of multiple layers of coiled metal, providing greater strength and load-bearing capacity compared to single-layer slotted pins. This design makes them highly resistant to shear forces and deformation.These pins can be installed with minimal tools, often requiring only a hammer or press. Their ability to compress during installation reduces the need for precise machining of holes, simplifying assembly and reducing costs.
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.
