High performance construction fasteners in metal applications
Allflex™ stainless steel thread cutting and self tapping screws are made in the USA and have a proven success record in architectural applications worldwide. They are available in both 302ss and 316ss in diameters from #10 through 3/8”.
They are the ideal fastening solution for curtain walls, windows, doors and other applications that feature a dissimilar metal, such as aluminum. High quality stainless steel coupled with the Stalgard® GB coating gives Allflex™ superior protection in the harshest environments.
Allflex™ fasteners are first manufactured from 300 series stainless steel, which offers high resistance to degradation, seen as rust and then coated with Stalgard ® GB which preserves the integrity of the joined metals by providing a barrier between the steel and aluminum. Whenever dissimilar metals such as steel and aluminum are joined in the presence of water whether from rain, condensation, salt spray, etc. the electrolytic reaction can be ruinous. Allflex™ fasteners’ combination of material and coating helps protect both the fasteners and application material to both prevent joint failure and retain a high aesthetic quality.
Some benefits of Allflex fasteners:
-Type B and AB tapping screws, Type F and 23 thread cutting screws, primarily in aluminum components eliminate tapping operations, allowing for faster installation.
-Stalgard® coating prevents Galvanic reaction between stainless steel fasteners an aluminum components.
-Stainless steel fasteners offer long term corrosion resistance in aggressive environments, including coastal areas.
-The specific combination of features retains joint and material integrity to help insure long term quality.
Curtain Walls, including aluminum panels. Windows and Doors. Structures in pool and spa areas. Hurricane protection systems. Explosion control systems. Buildings in a marine environment.
