CONFAST 1/4" x 2-3/4" Flat Phillips Concrete Screw with 2 Drill Bits (200 per Box)

ApplicationsThe anchor is made from Carbon Steel, and is Blue. This anchor is designed for use in Concrete, Block, and Brick.EnvironmentThe anchor is designed for use in a Dry environment.Head Style The anchor is a Flat Countersunk Phillips head and is designed to prevent the head from protruding above the surface of the item being attached.Hole Diameter/Bit DiameterThe anchor requires a 3/16" 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 RequiredA #3 phillips bit 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 2-3/4"Thread LengthThe length of the threads on the anchor is 1-3/4" in length.Minimum EmbedmentThe minimum anchor embedment into the concrete is 1". Therefore, the anchor must be installed so that a minimum of 1" of the anchor is embedded into the concrete.Maximum Fixture ThicknessThe maximum fixture thickness or the maximum thickness of the material being fastened for a anchor is 1-1/4" to 1-3/4". This will ensure that the minimum embedment of 1" will be met.Fixture Hole DiameterThe 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 5/16".Spacing between AnchorsEach anchor must be spaced a minimum distance of 4" from each other when measured center to center.Edge DistanceIt is very important not to install the anchor any closer than 3" from an unsupported edge of the concrete.
