Thanks to the integrated collar surface (flange), these nuts offer an enlarged contact surface that optimally protects the component and evenly distributes the forces that occur. In combination with a high strength class, they are ideal for friction-locked connections with high tightening torques.  <\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243;
