How to use

Drill a hole of the appropriate diameter and depth into the concrete using a hammer drill and a carbide masonry bit. Clean the hole from dust and debris before inserting the screw. Position the fixture, align the screw and drive it in using the correct screwdriver or socket until the head is flush or achieves the specified embedment depth. Maintain perpendicular alignment during installation and avoid overtightening to prevent damage to the base material.

Usage recommendations

Select a drill bit diameter and drilling depth that match the screw's required hole size and embedment. Use personal protective equipment and follow safe drilling practices. For load-critical or seismic applications, consult relevant standards or an engineer to confirm suitability and required spacing and edge distances.
