What is a Spring pin?

A spring pin is a type of fastener primarily used to secure machine components, particularly known for its ability to withstand dynamic loads and vibrations. This pin is typically a cylindrical metal piece with a spring mechanism inside, featuring openings at both ends. After being inserted into a hole, the spring pin compresses due to its elasticity, pressing the pin against the walls of the hole and ensuring a firm fixation. Due to this characteristic, spring pins serve as an easy-to-remove connection method in assembly operations for machines and structures. They are widely used across various industries, including automotive, industrial machinery, and electronics. One of the advantages of spring pins is that they can be installed quickly without tools, enhancing work efficiency.

Moreover, spring pins are often made from materials with high corrosion resistance and wear resistance, allowing them to maintain reliability even in harsh environments. In this way, spring pins play a crucial role in various applications as essential components.

Application of Spring pin

１．Automotive Parts: Spring pins are used to secure components in the suspension system of vehicles, providing strong resistance to vibrations and stable performance.
２．Electronics: Spring pins are utilized to hold components on printed circuit boards, allowing for easy removal and replacement.
３．Industrial Machinery: In factory production lines, spring pins are employed to connect machine parts, facilitating quick disassembly during maintenance.
