Concrete Screw Anchors 3/8 x 4" ScrewsZinc Plated Steel

Concrete Screw Anchors have been designed for standard ANSI tolerance drill bits. Tough threads for tapping high strength concrete

Step 1: Using the proper drill bit size, drill a hole into the base material to the required depth. The tolerances of the drill bit used should meet the requirements of ANSI standard B212.15

Step 2: Remove dust and debris from hole after drilling to extract loose particles created during drilling.

Step 3: Select a torque wrench or powered impact wrench and do not exceed the maximum torque. Attach an appropriately sized hex socket/driver to the impact wrench. Mount the screw anchor head into the socket.

Step 4: Drive the anchor into the hole until the head of the anchor meets the fixture. The anchor must be snug after installation. Do not spin the hex socket off the anchor to disengage.
