Introduction to Spring Pins
Spring pins, also known as roll pins or slotted pins, are mechanical fasteners with a coiled or slotted design. They are typically made of materials such as steel, stainless steel, or brass. Spring pins are used to secure components together in a variety of applications, including automotive, aerospace, machinery, and electronics. Their unique design allows them to expand slightly when inserted into a hole, creating a tight fit and providing reliable retention. They are easy to install and remove, making them a popular choice for many industries.
