*Pilot bores are to be drilled into the part. Minimum values for d1 and d2 are given by the minimum bore diameter values in the MIKI PULLEY standard hole-drilling standards and maximum values from the maximum allowable drilled bore diameters.
*The nominal diameter for the bolt M is equal to the quantity minus the nominal diameter of the screw thread.
