Metric standard SUS304/316 stainless steel sleeve anchor expansion bolt

Description:

Concrete Sleeve Anchors' design allows them to anchor into concrete, brick and block. 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.

sleeve anchor is the branch pipe / crane / bracket or device fixed on the walls, floor and column with a special screw thread connecting piece.

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.

Specification:

Application:

The length of the sleeve anchor should be equal to minimum embedment, plus fixture thickness, plus nut and washer. The Sleeve anchor requires no maximum hole depth. The depth of the hole in the base material should be at least the length of the sleeve anchor minus the thickness of the material being fastened. This will provide some extra depth to accommodate a minor amount of concrete cuttings which may not be able to be cleaned out of hole.

Advantages:

The forces on a Sleeve Anchor are transferred to the material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchors. 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.
