Installation instructions1


NOTE:  Failure to abide by these instructions may void any warranty provided by Evolution Fasteners (UK) Ltd. This document does not alleviate the user, designer or any other party from their respective obligations under the terms of the Warranty2. The use of impact tooling voids the Warranty.


  1. Clear installation area of dirt and debris and ensure that there are no other contaminating substances (i.e. oil, grease, etc),
  2. Using a non‐impacting TEK screwdriver (such as Makita FS2500), insert the screw into the fixture and substrate material perpendicularly (± 5˚ from the normal) using not greater than 1,500 RPM and a steady pressure on the tooling only (do not force the tool, allow the screw to cut),
  3. Stop inserting the screw once the underside of the flange makes contact with the topside of the fixture material for non‐washered screws. For washered screws continue inserting until the compression disc of the washer changes from convex to flat. There should be no torque applied to the fasteners post‐installation.
