Technical Specifications

Split drive anchor technical information should be considered before installation to ensure proper setting. There are two anchor heads available - flat countersunk and round head. These fasteners should be used in solid concrete and dead loads only. Split Drive anchors are made of high strength steel alloy which is zinc plated and tamper resistant. To determine length: add minimum embedment 1-1/8" plus thickness of material to be fastened.

*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.
