Sleeve Anchors/Concrete Anchors/Anchors/

Sleeve Anchors

Sleeve anchors come in different styles such as: Acorn nut style, Flat head style and Hex nut styles.

Sleeve anchors work by expanding against the material in which it is embedded. When the head is turned clockwise, the conical end is pulled into the sleeve, pushing it outward 360 deg around the anchor into the masonry.

They are designed to be used in solid or hollow masonry, including cinder block, brick, marble and concrete. One advantage of sleeve anchors is that it can be removed after it’s been installed. Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor. The sleeve anchor is preferred when a decorative finish look is desired.

How Sleeve Anchors Work

Considered by many in the construction trade and other industries to be one of the most versatile masonry expansion anchors available, sleeve anchors can be used in a variety of base materials, including block, brick, and concrete. Sleeve anchors come in a wide variety of diameters, lengths and head styles, which makes them an excellent fastener solution for light or heavy-duty fastening jobs. They are also pre-assembled and ready for immediate installation.

The anchor sleeve is constructed of high-quality steel components. Each part has zinc plating and comes pre-assembled in a ready-to-use anchor. The anchor consists of a threaded stud that has an outwardly flared, cone-shaped end. The tubular expander sleeve is assembled over the stud and pushed against the tiny diameter of the cone. The washer and hex nut assembled on the stud complete the anchor, which functions based on a true expansion principle: By tightening the nut, it pulls the cone-shaped stud end into the expander sleeve. This process wedges the anchor and locks it into the base material.
