They come completely assembled and ready to use. The hole diameter in the base material which must be drilled for the cement sleeve anchor is equal to the diameter of cement sleeve anchor being used. The diameter of sleeve anchor to use is determined by the hole in the fixture being fastened and the holding values required for the particular application.
Cement sleeve anchors are available with a number of different heads types that meet very specific applications requirements. The head styles available are acorn, hex, flat and round. Cement Sleeve Anchor Information Cement Sleeve Anchor Installation and Video Cement Drop-In Anchor Cement drop-in anchors are a female type cement anchor that is designed for use in solid concrete and cannot be used in brick or block base material.
The cement drop-in anchor is primarily used with a threaded rod and for installations in the ceiling for hanging electrical trapeze, for ductwork or for other mechanical apparatus used in the construction of commercial buildings.
The cement drop-in anchor can be used as a flush mounted anchor in conjunction with a standard bolt that allows for bolting and unbolting. There are four options available that can be used in concrete block: 1 Stud-type anchor: where the stud will stick out from the wall.
Example: Sleeve Anchor 2 Hammer-type anchor: where the stud does not protrude from the wall, for a finished look. Example: Hammer Drive, Nylon Nail-It 3 Female-type anchor: where a screw is inserted into the anchor for a finished look. If using a stud-type anchor, female type anchor, or the concrete screw- the fixture, or item being fastened, can be removed at any time with little or no damage to the concrete block.
However, hammer-type anchors are permanent installations. Removing these fasteners will greatly damage the concrete block and possibly the fixture as well. Stud-Type Anchor - Fixture will be removable Sleeve anchors come in the widest variety of sizes for applications that fall into this category. An engineer should be consulted every time concrete anchors are used for heavy loads.
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. The sleeve anchor also comes in a variety of head styles - hex head, flat countersunk and acorn or round head for aesthetics.
Hammer-type Anchor - Fixture will be non-removable The hammer drive and nylon nail-it anchors are two fasteners that fall into the hammer type category. Neither of these anchors results in a stud protruding from the wall. Both of these anchors are basically non-removable. The hammer drive anchor is produced with a low profile, mushroom head while the nylon nail-it anchor is available in three head styles - mushroom, round and flat countersunk. Female-type Anchor - Fixture will be removable There are a number of different female type anchors.
The anchor chosen will depend on the type of bolt being inserted into the anchor as well as the quality of the base material. The sizes of these anchors are designated by the inside diameter of the anchor, which is the size of the bolt that will be inserted into it.
The different female type anchors and their unique characteristics are listed below:. The machine screw anchor requires a machine threaded bolt with national coarse threads. Use the length of the sleeve anchor, which needs to equal the minimum embedment, and then add the fixture thickness, nut and washer lengths. The sleeve anchor does not require a maximum hole depth, but the depth of the hole into the base material should be at least the length of the sleeve anchor minus the thickness of the material being fastened.
This equation will provide a bit of extra depth to accommodate that small amount of concrete cuttings that perhaps were unable to be retrieved from the hole.
It might not be commonly acknowledged, but if the sleeve anchors are spaced too close to each other, their holding power may be reduced due to the interaction of forces in the material.
Anchors should be spaced a minimum of ten anchor diameters apart and five anchor diameters from an unsupported edge.
