Applications The anchor is made of carbon steel, and is galvanized. This anchor is designed for use in concrete, blocks, and Brick. Environment The anchor is designed for use in a dry environment. Type Head The anchor is a flat countersunk head and is designed to prevent the head from sticking out above the surface of the object to be connected. Hole Diameter / Bit Diameter The anchor requires a 3/8" hole to be drilled in the base material (concrete, blocks and bricks). The hole must be drilled with carbide bit drill which meets ANSI standards and used in a drill hammer. Anchor diameter the dowel diameter is 3/8". Anchor length Anchor length is 5" Minimum embedment The minimum anchor embedment in concrete is 1-1 / 4" . Therefore, the anchor must be installed so that a minimum of 1-1/4" of the anchor is embedded in the concrete. Maximum Fixture Thickness The maximum thickness of accessories or the maximum thickness of the material be fixed for an anchor is 3-3/4" . This will cause the minimum rooting of 1-1/4" will be achieved. The hole in the device or material being fixed must be greater than the designated diameter of the anchor. The 3/8" anchor diameter requires hole in the device both 1/2" . Distance between anchors each anchor shall be spaced by a minimum distance of 3-3/4" between them when measured from center to center. Edge Distance It is very important not to install the even closer than 1-7/8" from an unsupported edge of the concrete.
