Technical Information

There are a number of technical elements that must be considered when working with split drive anchors. These anchors can work with high levels of 3,000 psi Pull out and Shear. Split anchors are manufactured with hardened, heat-treated carbon steel. The anchor has two sheared, pre-expanded halves at the base. This split drive anchor structure produces tremendous force upon the inside walls of the hole, resulting in low "slip" rates and high vibration resistance.

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. Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity.
