Spring pins are a common type of fastener used to join or align two or more parts of a machine or assembly. They are designed to absorb shock and vibration while maintaining a secure connection between the parts. There are two main types of spring pins: slotted and coiled.
Slotted spring pins are made from thin, flat spring steel and have two slots cut into them. These slots allow the pin to compress slightly when it is inserted into a hole, creating a tight and secure fit. Slotted pins are easy to install and remove and are commonly used in low-stress applications.
Coiled spring pins, on the other hand, are made from a single piece of round wire that has been coiled into a spiral shape. They have a uniform diameter along their entire length and can be inserted into a hole without the need for slots or other modifications. Coiled pins provide a more consistent and reliable holding force than slotted pins and are ideal for high-stress applications where vibration and shock are a concern.
Overall, both slotted and coiled spring pins are effective fastening solutions that can be used in a variety of applications. The choice between the two will depend on the specific requirements of the application and the amount of stress the pins will need to bear. Regardless of the type chosen, spring pins are an excellent choice for maintaining a secure and reliable connection between parts.
