Installation Guide
Simple 4-Step Installation
Concrete screw anchors are designed for fast and reliable installation into pre-drilled holes in concrete.
-
STEP 1 — Drill
Drill the hole using the specified carbide drill bit.
-
STEP 2 — Clean
Remove dust and debris from the hole.
-
STEP 3 — Drive
Drive the anchor through the fixture into the concrete.
-
STEP 4 — Set
Install until the anchor head contacts the fixture. Apply recommended torque where required.
Installation Checklist
