Technical Specifications
Before installing concrete sleeve anchors, it is important to consider a number of technical specifications. These concrete fasteners come in three different head styles: acorn, hex, and round. Ultimate holding values, anchor length, and minimum embedment will determine the size and type of sleeve anchor needed. They provide 360° of contact which reduces the stress that causes anchor wear and tear over time. Tension and concrete shear pounds are also determining factors when working with sleeve anchors. See the Ultimate Holding Value charts below to read more about the technical specifications of these anchors.

*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.
