[2] Load Attachment
Utilize the threaded part on the rod tip to attach the load. Screw in the load or use the enclosed
nut. The enclosed nut can also be used as a stopper to stop from loosened after the load is
screwed in.
Maximum nut tightening torque of metal part on rod tip (Note 1)
• RA4 31.9N•m
• RA6 88.8N•m
Note 1 Listed above are the maximum nut tightening torques in the basis of the metal part on
the tip of the rod. Tighten the nut with the appropriate torque below those values
considering the condition of the load attachment. In case the load is a material other
than steel, such as aluminum, or the area of the tightening contact surface is small,
consider the limit interface pressure of the material of the load and set the appropriate
torque below the limit value.
