The actuator mounting surface should be machined or otherwise processed to a smooth surface
of equivalent preciseness.
x The effective depth varies depending on the actuator model and mounting surface. Determine an appropriate
length for the screws to be used by referring to the figure below.
x Circular and long positioning pin holes are provided in each mounting surface. Use these holes if necessary.

About the tightening screws
x Use hexagonal socket head bolts for the male base mounting bolts.
x It is recommended to use high-tension bolts of ISO 10.9 or higher strength.
x Make sure the effective engagement length between the bolt and female thread is equal to or greater than
either of the following values, whichever is applicable:
Female thread is made of aluminum Æ Twice the nominal diameter
Caution: Some tapped mounting holes are through holes. Never use long screws exceeding the effective
thread length.
Such long screws may damage the internal mechanism or electrical parts.
