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: Be careful when selecting the bolt length. If bolts of inappropriate lengths are used, actuator
mounting strength may become insufficient, or contact with driving parts may occur, resulting
in lower precision or unexpected accidents.
