Coiled Spring Pins | SPIROL

SPIROL invented the Coiled Spring Pin and its production technology in 1948. Since that time, the Coiled Pin has proven to be the most versatile Spring Pin in the industry. Easily recognized by its unique 2 1/4 coil cross-section, Coiled Pins are self-retaining fasteners achieved by radial tension applied against the hole wall, and they are the only press-fit pins designed to remain flexible after installation. 
 
Otherwise known as Spiral Pins, Coil Pins, Roll Pins or simply Spring Pins, SPIROL offers Coiled Spring Pins in both inch and metric sizes in a variety of materials and finishes from 0.8mm / .031” (1/32) in diameter up to 20mm / .750” (3/4) in diameter. 
 
SPIROL offers Coiled Spring Pins in three different duties, light duty, standard duty and heavy duty, to match the required strength and flexibility for each application.
