3.5.4 S-RT5 + M9 SCREW FASTENING SYSTEM
3.5.4.1 PRODUCT DESCRIPTION
The Hilti S-RT5 + M9 fastening system consists of the new and improved SDT 9 stand-up screw fastening system and the new S-RT5 + fasteners in collated strips .
The SDT 9 decking system can be powered with either the ST 1800 Adjustable Torque Screwdriver or the ST 1800-A22 Cordless Adjustable Torque Screwdriver . This system can perform both metal deck to frame attachment and deck sidelap connections .
Hilti S-RT5 + steel deck fasteners comply with ANSI / SDI RD1.0 , C1.0 and NC1.0 standards .
PRODUCT FEATURES AND BENEFITS
• Equivalent diaphragm shear performance as compared with the X-HSN power – actuated fastener , based on full scale diaphragm testing
• Improved pullover , leading to better performance under wind uplift thanks to large integrated washer
• S-RT5 + has Racing Tip technology provides best in class drill tip , optimized for fast drilling
• SDT 9 system provides ergonomics and balance and robust screw separation for a jam-free experience
