Slotted spring pins are headless cylinder shaped tube with a slot that runs down the middle of the pin. Slotted spring pins are also known as tension, roll, and expansion pins. They are to be installed in holes slightly smaller than the outside diameter of the pin. While being inserted, they compress against the wall of the hole.
Also in the spring pin family is coiled spring pins. They come in light, standard, and heavy duty. They operate in the same manner of slotted spring pins. Instead of having a slot in the middle of the pin, coiled spring pins are rolled to two and a quarter compression.
