Sleeve anchors are highly versatile fasteners used for securing fixtures into concrete, brick, and block. They are commonly used in light to heavy-duty applications such as mounting handrails, shelving, and heavy machinery support structures.
Unlike expansion anchors which create mechanical tension against the walls of the drilled hole, chemical anchors use a resin-based adhesive bond. This reduces stress on the base material, making them ideal for close-to-edge installations and weaker substrates like masonry or lightweight concrete.
Drywall anchors are specifically designed for hollow walls where solid concrete or studs are not present. They expand or toggle behind the drywall board to distribute the load weight evenly, preventing damage to the plasterboard.
Heavy-duty anchors should be used when safety-critical structural loads are involved. They feature robust steel sleeves and high-grade bolts designed to withstand high shear forces, seismic activities, and tensile loads in cracked or uncracked concrete.
The load capacity depends on several critical factors: the compressive strength of the concrete base, the embedment depth of the anchor, the diameter of the bolt, and the spacing distance between adjacent anchors and edges.
