Coiled spring pins provide design solution
The use of standard duty coiled pins as hinge pins in a circular saw blade guard application was causing problems during manufacture due to the high insertion forces.
When Spirol was asked to come up with an improved design solution, no shear strength requirements for the coiled pin were supplied. An option that required no changes to the automation equipment or the hole sizes in the components, was to change to a light-duty coiled spring pin.
