What is Fastening on Steel?
The Fastening on Steel (FoS) system consists of three types of corrosion-resistant studs from Hilti – S-BT HL, X-BT HL, and F-BT (Cordless Stud Fusion). Each method offers unique benefits for fastening onto steel structures in various applications.
-
S-BT HL threaded studs are screwed directly onto painted steel structures, offering a quick and reliable solution without the need for surface preparation.
-
X-BT HL threaded studs are fastened by friction welding, providing a highly secure bond even on painted or coated surfaces.
-
F-BT (Cordless Stud Fusion) is the latest advancement in fastening technology. Using a cordless, battery-powered tool, the stud is fused to the steel surface through a high-temperature process, ensuring a strong, corrosion-resistant connection. A complete fastening point solution includes a sealing washer for corrosion protection and a safety flange nut for a more reliable threaded connection. Portable, cordless system – eliminates the need for long power supply cords. This method is particularly advantageous in areas where portability and ease of use are critical. Little-to-no rework necessary on back of coated steel – corrosion protection remains intact.
FoS is especially suitable for field support and late-stage modifications across multi-discipline applications, including grating and earthing/bonding of electrical systems. The entire installation process uses battery-powered tools, making grinding, welding, and repainting unnecessary.
