Tightening screws
x Use hexagonal socket head bolts for the male threads for installing the base.
x Use of high–tension bolts meeting at least ISO 10.9 is recommended.
x 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
Female thread is made of aluminum ĺ 1.8 times of nominal diameter
Caution: Pay attention when choosing the screw length. In case that insufficient length of screws is chosen,
it may cause such problems as the strength not being enough on the actuator attachment,
interference with driving part, drop in accuracy performance and unexpected accidents.
