Applications The anchor is made from 304 Stainless Steel. This anchor is designed for use in Concrete only, and should never be used in block or brick base material. Environment The anchor is designed for use in a Submerged/Chemicals environment. Hole Diameter/Bit Diameter The anchor requires a 3/4" hole to be drilled in the base material (Concrete only). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill. Diameter of Anchor The diameter of the anchor is 3/4". Length Anchor The length of the anchor is 5-1/2" Thread Length The length of the threads on the anchor is 3" in length. Minimum Embedment The minimum anchor embedment into the concrete is 3-1/4". Therefore, the anchor must be installed so that a minimum of 3-1/4" 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 1-1/2". This will ensure that the minimum embedment of 3-1/4" will be met. Fixture Hole Diameter The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 3/4" diameter anchor requires the hole in the fixture to be 1". Torque Value To be set properly in the concrete, the anchor must be torqued to between 150 - 175 ft./lbs. Spacing between Anchors Each anchor must be spaced a minimum distance of 7-1/2" from each other when measured center to center. Edge Distance It is very important not to install the anchor any closer than 3-3/4" from an unsupported edge of the concrete.
