A sleeve anchor is a type of mechanical fastener used to secure materials to concrete, brick, or other masonry surfaces. It consists of a cylindrical metal sleeve, usually made of steel or zinc-plated steel, with a cone-shaped end and a threaded bolt.

The sleeve is inserted into a pre-drilled hole in the masonry, and as the bolt is tightened, the cone-shaped end of the sleeve expands against the sides of the hole, creating a secure anchor point. This expansion also helps distribute the load over a larger area, providing a stronger hold than other types of fasteners.

Sleeve anchors are commonly used in construction and renovation projects to attach fixtures such as handrails, shelving, and signage to walls, ceilings, or floors. They are also useful for securing heavy equipment or machinery to concrete surfaces.

It’s essential to choose the right size and type of sleeve anchor for the intended application, taking into account the weight and load-bearing requirements of the fixture or equipment being attached. The hole should be drilled to the correct diameter and depth to ensure a proper fit and maximum holding strength. It’s also important to follow the manufacturer’s instructions carefully for installation and use.
