Technical Specifications for Sleeve Anchors

Technical Specifications for Sleeve Anchors

Purchase Sleeve Anchors

Before installing concrete sleeve anchors it is important to consider a number of technical specifications. First, consider the four head styles: acorn, hex, flat and round. Ultimate holding values, anchor length, and minimum embedment will determine the size and type of sleeve anchor needed for a specific application. The sleeve anchor can be installed in solid concrete, brick or block base material. The hole to be drilled in the base material is equal to the diameter of the sleeve anchor being used.

Length: To determine the length of sleeve anchor required, add the thickness of the material to be fastened, plus minimum embedment, plus the thickness of the nut and washer. The sum of these three items equals the minimum sleeve anchor length. The Sleeve anchor requires no maximum hole depth. The depth of the hole in the base material should be at least the length of the sleeve anchor minus the thickness of the material being fastened. This will provide some extra depth to accommodate a minor amount of concrete cuttings which may not be able to be cleaned out of the hole.

Spacing: The forces on a Sleeve Anchor are transferred to the material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor. As a rule of thumb, the expansion anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact is part of the load conditions, the spacing should be increased.
