Spirol has helped an automotive supplier switch from using a semi-tubular rivet to a coiled spring pins, thereby eliminating problems with crimping.
A major supplier to the automotive industry is now using coiled spring pins from Spirol Industries as a hinge pin in an automotive glove compartment handle application - instead of using a semi-tubular rivet. The coiled spring pins were specified following major problems experienced during the crimping operation of the rivet. A fastening was needed that would meet the application requirements and eliminate the crimping problems.
Design advice from Spirol resulted in the replacement of the long semi-tubular rivet with two coiled pins. Spirol's standard-duty coiled pin was chosen for this application as it provided similar resistance as the rivet when the hinge was actuated. The coiled pin is self-retaining, which eliminates the need to crimp the fastener to ensure that it remains in the hole.
Full details of Spirol's coiled spring range are available in literature directly from the company.
