Regarding attachment screws
• Use of high-tension bolts meeting at least ISO-10.9 is recommended.
• Make sure to have the length of at least 1.8 times to the bolt diameter for the effective length of

Caution: Pay attention when selecting screws. If a bolt out of the instruction is used, it may
cause damage on tapped holes or unexpected accident or failure due to insufficient
strength on the actuator attachment.
