Clamp Screws

• The male screws for mounting the base should be M4 for SA5C, M5 for SS7C/SA6C/SA7C, and M8 for
SS8C/HS8C. (Use hexagon socket-head bolts.)
• For the bolts, we recommend high strength bolts of ISO-10.9 or higher.
• When using a foot base to attach to a mounting table, use the special washer made for high strength bolts that
comes with the actuator if the bolt is M8 or larger. This is unnecessary for M6 or smaller bolts. Do not use a
common spring washer.
• The recommended screw torque is given below.
