4,2х16 mm wafer head screw, selfdrilling
Wafer head screws are used both for fastening all the flashings of the metal buildings and for fastening facade and roof sheets with the "click" system.
The screw has a drill, which allows attachment to profiles with a thickness of up to 3-4 mm. The drill allows drilling with very little pressure, which is preferable in awkward positions and slipping of the screw on the metal. Also, the low profile head does not raise the next sheet covering it when laying facade and roof sheets.
All BAUFIX screws are characterized by a proven penetration ability, which reduces the screw losses to practically zero. This, along with the time saved, ultimately brings the price down almost to that of lower quality screws.
The screws are tested and their characteristics are fully documented. Based on these tests, we issue a Declaration of Performance.
The screws are also highly appreciated by our customers abroad.
