ETA FIRE RESISTANCE SEISMIC ISO

 

The Joker concrete screw with a truss head offers a robust anchoring solution that allows for quick and easy installation while providing excellent corrosion resistance and high load capacity.

It’s ideal for securing air conditioning units, charging stations, sprinkler systems, railings, and gym seats.

With ETA approval, it can be used in both cracked and uncracked concrete, as well as in precast prestressed hollow core slabs, and meets the F120 fire resistance classification for added safety.

Available in zinc plating and a silver-ruspert coating that withstands 1000 hours of salt spray testing.

Building materials

  • Concrete C20/25 to C50/60, cracked and non-cracked
  • Prestressed hollow core concrete slabs, strength C30/37
  • Stone
  • Brick
  • Masonry
  • Solid

How to installation 

  1. Drill a hole in the base material, the hole should be drilled deeper than the screw embedment depth according to our ETA installation instruction (pilot hole required)
  2. Clean out the hole of all debris.
  3. Insert the pointed end of the concrete screw through the fixture and into the hole in the base material.
  4. Drive the screw or use powered impact wrench slowly, allowing the threads to tap into the base material.
