3.2.15 S-BT HL FASTENING SYSTEMS
3.2.15.1 Product Description
The Hilti S-BT HL Fastening System is an innovative method of fastening to steel or a aluminum base materials . The system consists of threaded stud fasteners and matched installation tools which help ensure proper setting of the fasteners .
The S-BT HL fasteners are manufactured from carbon steel or stainless steel with thread diameters 8 mm ( M8 ) and 3 / 8 " ( W10 ). Carbon steel studs are supplied with an aluminum sealing washer Ø10 mm , stainless steel studs are supplied with a stainless steel sealing washer Ø12 mm , both with an EPDM sealing ring , and are cleanly set in a pre-drilled hole in the base steel . The S-BT system is designed to work on carbon steel from 1 / 8 " to 3 / 16 " thick with a pre-drilled
