Head Style The anchor is a Hex Washer Serrated head and is designed to allow the head to sit on top of the surface of the item being attached. Hole Diameter/Bit Diameter The anchor requires a 3/8" hole to be drilled in the base material (Concrete). The hole should be drilled with carbide tipped bit using a hammer drill.

Length Anchor The length of the anchor is 4" Minimum Embedment The minimum anchor embedment into the concrete is 1-1/2". Therefore, the anchor must be installed so that a minimum of 1-1/2" of the anchor is embedded into the concrete. Maximum Fixture Thickness The maximum fixture thickness or the maximum thickness of the material being fastened for a anchor is 2-1/2".
