2 Hole characteristics 2.1 Clearance application 2.1.1 Clearance holes as defined in Table 1 shall be used for all general joint applications using non-fitting fasteners Figure 1.
2.1.2 The PD shank bolts quoted in Table 1 shall comply with the EN series. 2.2 Close clearance applications On all rotating components and engine flanges, where it is unnecessary to have a fitted application. The close clearance holes defined in Table 4 with close tolerance shank bolts Figure 2 shall be used. This is required to obtain the good balancing characteristics needed for rotating assemblies and to ensure that joints cannot twist during assembly and cause misalignment of casings or rotors.
2.3 Fitted application It is recognized that for mainshaft flanges, bolted discs and similar rotating applications,
