Sleeve Anchor

Sleeve Anchor is a pre-assembled heavy-duty expansion fastener consisting of expansion sleeve, bolt, flat washer and hex nut, engineered for permanent high-load fastening on solid concrete and dense stone substrates.

The expansion sleeve features multiple longitudinal expansion slits and anti-slip embossed texture. Insert the complete anchor assembly into pre-drilled holes, then tighten the hex nut to pull the bolt. The conical tip at the bolt end forces the slotted sleeve to expand outward, tightly gripping the inner wall of the hole to deliver reliable friction lock with outstanding tensile and shear resistance.

All carbon steel components are finished with yellow zinc plating to form a dense anti-rust layer, providing long-lasting protection against moisture and dust erosion for both indoor and outdoor applications. Supplied as a fully assembled unit, it removes the need for separate part matching and greatly speeds up field installation work.

This anchor is widely adopted in construction and mechanical projects that demand stable heavy load capacity, including machinery supports, external curtain walls and safety handrails. A full range of standard sizes covers most medium and heavy-duty fixing requirements across building and mechanical installation works.

Custom sleeve lengths are available to fit varying wall thickness specifications. Every finished sleeve anchor undergoes pull-out load testing and salt spray corrosion inspection prior to delivery, fully complying with safety anchoring standards for construction and mechanical engineering projects.
