Why we use screws

Contemporary concrete screws are specifically designed to embed into substrate and stay there.

No wall plugs are required. This is why Firefly use concrete screws:

  1. Screws, applied with a tool, offer the highest pull out resistance of any fixing application against Premature Collapse*
  2. Screws provide the highest sheer loading of any fixing application**
  3. Screws work upside down in ceilings, or any other angle
  4. EACH TWIST OF A SCREW ADDS ADDITIONAL ANCHORAGE INTO SUBSTRATE OF ALL KINDS
  5. You have confirmation when you do up a screw that the hole is the right size and the fixing is tight
  6. With our fixings they do not become loose until that wall / ceiling etc fails
  7. We believe using a screw provides the best, secure, most reliable fixing

The impact of using a screw in Firefly clip application adds huge latent strength to the spring steel we use. This presses the clip closer into substrate in the event of a fire, for example,  when plastic trunking melts. WE cannot stress the importance of using concrete screws along with metal cable fixings loudly enough. THERE IS NO STRONGER SUBSTITUTE.
