Coil Spring
Spring Locating Pins are press-fit inserts that provide an extremely compact way to apply side force to a workpiece, for positioning or light clamping. The version, with a case-hardened Steel contact pin and a coil spring, is the most popular. A protective rubber seal around the contact pin keeps out dirt and chips. This type has the most travel, so it allows the most part-size variation.
