Spiral Tension Pins in Lightweight Design - Spiral Tension Pins

SPIROL invented the spiral tension pin in 1948. The spiral tension pin is a highly technically refined fastening element available in three versions: light, standard, and heavy, allowing designers to choose the optimal combination of strength, flexibility, and diameter that meets the varying base materials and application requirements. Its shock-absorbing design absorbs forces and vibrations to prevent damage to the hole and extend the lifespan of the component. Light version spiral tension pins are generally recommended for soft, brittle, or thin materials such as plastics, aluminum, die-cast, and ceramics, especially when the holes are located near the edge of the assembly. In situations where no significant loads occur, such as...
