The resilient characteristics of each coil in a
CoilThread Insert allows it to adjust independently to
secure the maximum surface contact with individual
threads in the parent material. As a result, loads are
distributed more evenly. Stress and fatigue
concentrations are reduced to maximize thread strength
and increase the reliability and life of the fastening
system.
