CONFAST 1/4" (Inside/Screw 1/4" - 20) Double Expansion Anchor (100 per Box)

ApplicationsThe anchor is made from Zinc Alloy. This anchor is designed for use in Concrete, Block, and Brick.EnvironmentThe anchor is designed for use in a Moist environment.Hole Diameter/Bit DiameterThe 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.Minimum EmbedmentThe minimum anchor embedment into the concrete is 1-3/8". Therefore, the anchor must be installed so that a minimum of 1-3/8" of the anchor is embedded into the concrete.Spacing between AnchorsEach anchor must be spaced a minimum distance of 5" from each other when measured center to center.Edge DistanceIt is very important not to install the anchor any closer than 2-1/2" from an unsupported edge of the concrete.
