Owners, architects and design engineers expect longer life cycles from buildings. Extended warranties and use of more sustainable materials add up to greater expectations for performance – from structural integrity to the purely aesthetic – of all building components. Bi-Metal structural screws and Bi-metal self-drilling tapping screws that provide the corrosion resistance of 300 series stainless steel and the efficiency of drill screws. Bi-Metal screws are suitable for use in both steel and aluminum.

Features and Benefits

• High strength, ductility and reliabliity
• Immune to hydrogen assisted stress corrosion cracking (HASCC)
• Higher corrosion resistance compared with carbon steel and 410 series stainless steel fasteners
• Stalgard RUSPERT coating creates greater galvanic compatibility in dissimilar metal applications, including connections involving aluminum
• 18-8 stainless compatible with pressure treated lumber

Specifications

• Outstanding corrosion resistance and long service life
• High strength, ductility and reliability
• Virtually immune to delayed embrittlement failures
• Greater galvanic compatibility in dissimilar metal applications involving aluminum
• Quickly drill and tap into steel or aluminum up to 1/2″ thick
• High in-place value over the life of structures, components and systems
