Length Of Sleeve Anchor For Concrete Block Wall

For example a 3 8 anchor requires a 3 8 hole to be drilled.

Length of sleeve anchor for concrete block wall.

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. If you need to hang a bracket or something else on a hollow concrete block wall you should consider using a metal sleeve anchor. The threads are hardened to cut the base material. Best for medium duty applications such as metal railing and grab bars set in concrete block.

Slip the concrete sleeve anchor into the hole. Masonry concrete anchors. Concrete screws are the generic name for a specially manufactured screw that taps threads into concrete brick or block. The expansion anchors can hold enormous weight.

The sleeve anchor needs to be expanded against the base material to achieve holding strength. 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. A typical three eighths inch expansion anchor which is embedded only 2 5 inches in a sound concrete wall can resist 1 200 pounds of pull.

An engineer should be consulted every time concrete anchors are used for heavy loads. Sleeve anchors require a hole that is the same diameter as the anchor being installed.
