Spirol® Slotted Spring Pins are headless hollow cylindrical tubes having a slot down the entire length with chamfered or round ends to aid installation. This type of pin is produced to a controlled outside diameter slightly greater than the hole in which it will be installed. Compressed as it is installed, the pin applies continuous pressure toward the sides of the hole wall, providing tension in a radial manner to prevent loosening created by vibration or shock. EFC International carries Spirol® Slotted Spring Pins that meet ISO, DIN, ASME-Metric, and ASME-Inch Standards.
ASME 18.8.4M TYPE B (METRIC) SLOTTED SPRING PINS have thicker walls and a slot running the full length of the pin, allowing even compression during installation. This creates continuous pressure toward the walls of the mounting hole, providing radial tension to prevent loosening from shock or vibration.
