A steel component with internal thread has a few slight distortions when it undergoes quenching-tempering processes. These small distortions affect assembly severely in the precision engineering. Using FEA software with its user subroutines, the position and contour of distortions which will be confirmed by subsequent experimental measurement are simulated. This result reasonably explains the assemble difficulty in enterprise manufacturing, and then lots of suggestions are given for manufacturing improvements.
