Description

TAP-FLEX® Thread Forming Sefl Tapping Structural Screws

Features

• Eliminates thread-tapping operations and allows for blind installations (e.g. HSS)

• High hardness lead threads for tapping into steel and aluminum

• E-Form® thread profile overcomes friction build-up and reduces drive torque

• Formed threads help resist loosening (e.g., vibration, thermal change)

• Serrations on underside of hex washer head lock against the fixture

• In the load-bearing area, a lower hardness heat treatment provides Grade 5 bolt mechanical properties, resulting in a fastener with increased ductility having no significant susceptibility to Hydrogen-Assisted Stress Corrosion Cracking (HASCC)

• Stalgard® Plus Coating provides improved corrosion resistance as well as enhanced galvanic compatibility in dissimilar metal applications, including those involving aluminum, compared with fasteners with standard zinc plating

• Fasteners coated with Stalgard PLUS typically show no red rust or other base metal corrosion on significant surfaces after 1500 hours of salt spray exposure in accordance with ASTM B117

Applications

• Hollow Steel Sections (HSS)

• Window Walls/Glazing

• Curtain Wall/Cladding

• Angles and Brackets

• Metal Infill Panels

• Stairs and Risers
