b
For hexagon screws with  anges (NF E 25-030-1) :
Apply an increased torque of +10%.
b
Where washers are used. the following coeffi cient is to be applied (FD E 25-502) :
-
Plate : +0% - Spring (or Grower) washer without jaws (W) : +10%
-
Smooth tapered washer (CL): +5% - Conical. internal teeth (CDJ-JZC) : +15%.
