Length Of Sleeve Anchor For Concrete Block Wall

This anchor is very versatile because there is a wide range of lengths available allowing materials of many different thicknesses to be attached to a block wall.

Length of sleeve anchor for concrete block wall. Length is measured from the washer to the end of the anchor. Sleeve anchors with diameters of 5 8 and 3 4 are usually considered heavy duty anchors. It is critical that the length of the sleeve anchor chosen does not protrude into the hollow section. The depth of the hole that is drilled into the base material must be a minimum of 1 2 deeper than the anchor will penetrate.

An engineer should be consulted every time concrete anchors are used for heavy loads. First drill the proper size pilot hole 3 8 in 1 2 in etc through the wood or metal and into the concrete. 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.

Sleeve anchors are designed for use in hollow base materials such block or brick. Masonry concrete anchors. It is a mechanical expansion anchor assembled with an expansion sleeve spacer nut and washer. For example a 3 8 anchor requires a 3 8 hole to be drilled.

The sleeve anchor needs to be expanded against the base material to achieve holding strength. Hold the object you re fastening firmly against the wall because the anchor will draw it only slightly tighter as you tighten the screw or nut. Sleeve anchors masonry concrete anchors. Concrete screws are the generic name for a specially manufactured screw that taps threads into concrete brick or block.

Sleeves pinch the side of the pilot hole and get tighter as the screw is driven into place. If you need to hang a bracket or something else on a hollow concrete block wall you should consider using a metal sleeve anchor. Sleeve anchors are also available in flat head and hex bolt head types. Slip the concrete sleeve anchor into the hole.

Sleeve anchors require a hole that is the same diameter as the anchor being installed. Tighten the fastener until it s secure. The sleeve anchor can be installed in solid concrete brick or block base material. Ucan sleeve anchor is a medium duty anchor ideal for applications in concrete hollow block and brick.

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. 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.
