Technical Specifications — Strike Anchor

Before installing strike anchors, certain technical specifications must be considered to ensure the correct size and length is used based on ultimate holding values, minimum embedment, spacing between anchors and minimum edge distance. Strike anchors are available in diameters ranging from 1/4" to 3/4" and a variety of lengths. Strike anchors are made from carbon steel and plated with a yellow zinc plating. Strike anchors should be used in solid concrete only.

Strike Anchor Length: Thickness of material to be fastened, plus minimum embedment, plus the thickness of the nut and washer equals the minimum length of the strike anchor.
