Measurement Techniques for the Inspection of Coiled Spring Pins

Coiled Pin design is such that the diameter will be within specification over a minimum of 270° of the circumference. This design characteristic ensures that diameter at the seam will remain equal to, or less than, that at any other point in the plane of rotation. This feature prevents the seam from damaging the host component.  This White Paper will walk you through how to measure the key characteristics of a Coiled Pin as well as recommend the proper measurement equipment.
