Description
Tap-Flex Thread-Forming Structural Screws are designed to offer a replacement option for traditional nut and bolt assemblies. These fasteners provide an excellent solution for blind connections. The patented E-Form® segmented thread profile design improves installation and forms threads that provide increased thread engagement.
• Hex washer head with serrations
• 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)
• 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)
Common applications include: hollow steel sections (HSS), window walls/glazing, curtain wall/cladding, angles and brackets, metal infill panels, stairs and risers
