Sleeve Anchors

Sleeve Anchor Technical Information:
The Sleeve Anchor is constructed of high quality steel parts. Each part is zinc plated and assembled into a complete ready-to-use anchor. The anchor consists of a threaded stud with an outwardly flared cone-shaped end. A tubular expander sleeve is assembled over the stud and butted against the small diameter of the cone. A washer and hex nut are then assembled on the stud to complete the anchor. The anchor works on a true expansion principle: Tightening of the nut pulls the cone-shaped stud end into the expander sleeve, wedging it outward and locking the anchor into the base material.
Sleeve Anchor use:
Concrete sleeve anchors are ideal for a large variety of uses. Sleeve anchors work by inserting them into a hole drilled into concrete. Turning the nut pulls the working end of the sleeve anchor up through the sleeve, expanding and anchoring itself securely in the concrete, brick or block. The anchors are available in zinc plated and stainless steel. Sleeve anchors come fully assembled and ready to use.
The forces on a Sleeve Anchor are transferred to the material that it is installed in. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor. As a rule of thumb, the expansion anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact are part of the load conditions, the spacing should be increased.
Reasons to Use Concrete Sleeve Anchors:
Can be installed through the object that is being fastened
No pre-spotting of holes
Base material does not need to be solid
Sleeve anchor diameter is hole diameter
Work in any depth hole
Wide range of selection
Easy to Use
Heavy-loading capacity
Provide 360-degree contact over a large area
Special Features of Sleeve Anchors:
Wide range of fixture thickness so there is no weakened shear area
360-degree hold contact for better pullout resistance and reduced concrete stress
