What are Sleeve Anchors?
Sleeve anchors are a type of anchor that consists of a sleeve that expands when the screw or bolt is tightened, creating a secure hold in the material it is being attached to. They are commonly used in concrete, brick, and block applications where the material is too hard or dense for other types of anchors. Sleeve anchors come in various sizes and types, including zinc-plated, stainless steel, and nylon, making them suitable for a wide range of applications.
The installation process of sleeve anchors is relatively simple. First, a hole is drilled into the material, then the sleeve anchor is inserted into the hole, and finally, the screw or bolt is tightened, causing the sleeve to expand and create a secure hold. Sleeve anchors are known for their high holding power and are often used in critical applications where safety is a top priority.
How Do Sleeve Anchors Work?
Sleeve anchors work by expanding when the screw or bolt is tightened, creating a secure hold in the material. The sleeve is made up of a cylindrical tube with a cone-shaped end that expands when the screw or bolt is turned. As the screw or bolt is tightened, the cone-shaped end of the sleeve expands, creating a secure hold in the material.
The holding power of a sleeve anchor is determined by the diameter of the sleeve and the material it is being attached to. A larger sleeve diameter provides a greater holding power, making it suitable for heavier loads. Sleeve anchors are available in different materials, including zinc-plated, stainless steel, and nylon, which affect their corrosion resistance and durability.
