Difference between wedge anchor and sleeve anchor

Wedge Anchors: Wedge anchors have tapered ends and are designed to be inserted into pre-drilled holes in concrete. When the bolt is tightened, the wedge-shaped end presses against the hole wall, forming a strong fixing force.

Sleeve Anchors: Sleeve anchors consist of a stud with a tapered end and a sleeve that expands when the bolt is tightened. The sleeve is inserted into the pre-drilled hole and as the bolt is tightened, the tapered end pulls the sleeve upward, causing it to expand and create a strong hold within the concrete.

In summary, wedge anchors rely on their wedge shape to create a strong hold, while sleeve anchors use an expandable sleeve to clamp the concrete. The choice between the two will depend on the specific requirements of the application and the type of load the anchor needs to support.
