The Series 550 Cosmetic Coiled Pin is a coiled spring pin designed for cosmetic hinge applications in compact cases, offering controlled swing torque and consistent hinge performance through uniform radial spring force. It features a beveled seam edge to eliminate high spots, low insertion force, and compression during installation to minimize stress and scrap. The pin is manufactured from stainless steel, has a plain oil-free finish, and is compatible with plastic hinges requiring precision-matched holes. Recommended installation guidelines include retaining 60% or more of the pin length in the inner hole, maintaining a minimum bearing surface three times the pin diameter, and ensuring the inner hole depth exceeds the retained length by at least 0.35mm. Misalignment between holes should not exceed 0.05mm. Installation is optimized with the Model HC dual pin inserter.
The unique flexibility of the Series 550 Cosmetic Pin, an extra light duty coiled spring pin, makes it the ideal fastener for light duty plastic hinge applications.
The use of a SPIROL Cosmetic Pin will simplify your design and manufacturing process. Assembly is easier, consistent and less expensive. Cracking, squeaking, and “floppies” will be eliminated.
