Applications The anchor is made from Anchor Body Antimonial Lead Alloy/Cone Zamac Alloy. This anchor is designed for use in Concrete, Block, and Brick. Environment The anchor is designed for use in a Moist environment. Head Style The anchor is a head Hole Diameter/Bit Diameter The anchor requires a 1/2" hole to be drilled in the base material (Concrete, Block, and Brick). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill. Driver Required A is required for driving the anchor into the base material. Diameter of Anchor The diameter of the anchor is 1/4". Length Anchor The length of the anchor is 7/8" Thread Length The length of the threads on the anchor is in length. Minimum Embedment The minimum anchor embedment into the concrete is 7/8". Therefore, the anchor must be installed so that a minimum of 7/8" 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 . This will ensure that the minimum embedment of 7/8" 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 1/4" diameter anchor requires the hole in the fixture to be 9/16". Spacing between Anchors Each anchor must be spaced a minimum distance of 5" from each other when measured center to center. Edge Distance It is very important not to install the anchor any closer than 2-1/2" from an unsupported edge of the concrete.
