CUP HOOK SLEEVE ANCHORS

A cup hook sleeve anchor is a medium-duty expansion fastener designed to provide a secure hanging or tie-down point in solid materials like concrete, brick, and stone. As you tighten the nut or hook, the internal cone pulls into the sleeve, expanding it against the walls of the pre-drilled hole for an instantaneous load-bearing grip. 

Performance Specifications
These anchors are typically manufactured from high-strength carbon steel with various finishes to resist corrosion. 
Materials & Finishes: Available in Zinc Yellow Passivated (gold) for moderate indoor protection. 
Load Capacity: Medium-duty performance. For example, a standard 8mm sleeve anchor can often support significant tensile loads; however, specific capacities depend on the base material (e.g., 32MPa concrete).
Dimensions: Diameter of 8mm to 12mm and length 40mm.
