Fastening on Steel (FoS)

System Overview

Post-paint modification opportunities

Hilti S-BT threaded screw stud and X-BT HL threaded friction welded stud is a highly corrosion resistant stud system designed for direct fastening to steel structures with painted surfaces. The system is named Fastening on Steel (FoS). FoS is especially suitable for field support and late-stage modification of multi-discipline applications, grating and earthing/bonding of electrical systems. FoS is quickly installed by use of battery powered tools and eliminates the need of grinding, welding and repainting the structure.
