About this item

• Self-tapping screws

  Self-tapping screws are screws assembled with sealing washers without drill points.
  
  Self-tapping screws seal the bore hole towards the outside and thus protect it from wetness. They are therefore mainly used in outdoor areas on facades or roofs. Since the screws do not have a drill point, a through hole must first be made in a previous work step. However, the thread is then formed automatically in the screwing process. This eliminates work steps and other tools such as tap drills or fastening elements such as nuts.
  
  Self-tapping screws are also differentiated according to whether they are fastened in timber or metallic/steel substructures. Depending on the substructure, they have different properties.
