Simple, reliable fixing in high tensile steel
Increasing demands in terms of security and product durability increasingly call for the use of high quality steel fasteners in industrial construction. Quite often, a range of different steel hardness grades are used on site. Conventional thread-forming screws may not thread form in these harder steel substrates. Often the threads will collapse during installation and become extremely difficult to use. But it’s no problem for SFS thread-forming fasteners, which maintain their complete functionality in every steel grade from S 235 to S 355.
