How to use
Select a drill bit size and drill a hole into solid concrete or masonry to the required depth and diameter recommended for a 40 mm masonry screw. Clean the hole of dust and debris, then insert the screw and tighten using an appropriate screwdriver or power driver until the head is flush with the fixture. Avoid over-tightening to prevent damage to the substrate or screw thread. For best results, follow standard installation practices for concrete screws and observe local load and spacing guidelines.
Usage recommendations
Use in solid concrete or masonry only; avoid hollow or highly cracked substrates. For exterior exposed applications consider additional corrosion protection. When fastening critical loads or heavy fixtures, consult relevant load tables and use appropriate anchors designed for the specific structural requirements.
