   1) primary inspection, a through check on raw materials before storage in warehouse; 
   2) routine inspection, a 15-minute frequency routine check with gauge in daily production; 
   3) completion inspection, a final check with gauge based on 5% of the total production quantity. 
   
    Besides the above, torque and fatigue testing is conducted after surface heat treatment.
