Technical Specifications
Single expansion anchor technical specifications must be considered before installing these concrete anchors. Anchor size refers to the diameter of the bolt used. These fasteners are made of zinc alloy and are completely rust-resistant. Single expansion anchors work well in medium to heavy duty applications and also in mediums of questionable strength. They can be used in dead, variable or vibratory loads. This type of concrete fastener can withhold 3000 PSI tensions of up to 11,600.

*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.
