• For the effective engagement length between the bolt and female thread, provide at least the
applicable value specified below:
Female thread is made of steel material ĺ Same length as the nominal diameter

cause damage on tapped holes or unexpected accident or failure due to insufficient
strength on the actuator attachment.
