Technical Specifications
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, and holding tensions. A strike anchor is available in a number of sizes including 1/4 in., 1/2 in., and 3/8 in. These concrete fasteners are made from carbon steel and plated with yellow dichromate. Strike anchors can hold up to 13,500 concrete shear pounds and should be used in medium to heavy duty applications.

*Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally
accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. *Tested by ATEC in accordance
with ASTM E488-90 and ICBO Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedment will
yield higher tension and shear capacity.
