*1: Bore size affects and limits the operating torque of the coupling.See the table “Bore Size and Operating Torque Term” on Page 6.*2: The Dimension for 4mm-7mm bores. For 8mm bore, the dimension is 0.236 inch or 6mm.
*3: The screw size and tightening torque for 4mm-7mm bores.
*4: The screw size and tightening torque for 8mm bore.
