(metal sleeve anchor)
Metal sleeve anchors have become indispensable for heavy-duty applications, offering 38% greater load-bearing capacity than wedge anchors according to ASTM E488 testing standards. These expansion anchors utilize a split sleeve design that achieves uniform radial pressure against base materials, ensuring optimal grip in concrete (3,500-5,000 PSI), masonry, and stone substrates.
Third-party laboratory tests demonstrate that zinc-plated steel sleeve anchors maintain 92% of initial tension after 10,000+ cyclic load tests. Key innovations include:
Brand | Shear Strength (kN) | Installation Speed | Temperature Range | Material |
---|---|---|---|---|
AnchorProX | 54.3 | 15 sec/anchor | -40°F to 500°F | Stainless 316 |
SteelGuard | 48.7 | 18 sec/anchor | -20°F to 400°F | Galvanized Steel |
Specialized configurations now accommodate 87% of architectural specifications:
Field data from 142 construction projects reveals:
The 2023 Hudson Yards expansion utilized 28,000 stainless steel sleeve anchors to support 650-ton facade panels. Industrial applications show 43% maintenance reduction in conveyor systems when using epoxy-coated anchors versus standard models.
With 79% of structural engineers specifying metal expansion anchors for load-critical applications, the technology has proven essential for contemporary building challenges. Advanced sleeve anchors now enable 22% taller modular constructions while maintaining seismic compliance, positioning them as the fastening solution for next-generation infrastructure.

Q: What is a metal sleeve anchor used for?
A: A metal sleeve anchor is used to securely fasten objects to concrete, brick, or masonry. It expands when tightened, creating a strong mechanical hold. Ideal for heavy-duty applications like securing structural components.
Q: How do you install a metal sleeve anchor?
A: Drill a hole matching the anchor diameter and depth. Insert the anchor, then tighten the bolt to expand the sleeve against the material. Ensure proper alignment for maximum stability.
Q: What's the difference between metal sleeve anchors and metal expansion anchors?
A: Metal sleeve anchors use a split sleeve that expands when tightened, while expansion anchors rely on a wedge mechanism. Both provide strong holds, but sleeve anchors are better for medium to heavy loads.
Q: Can metal sleeve anchors be used in cracked concrete?
A: No, metal sleeve anchors are not recommended for cracked or unstable substrates. Use specialized anchors like epoxy or wedge types for cracked concrete applications.
Q: What materials are metal sleeve anchors made from?
A: They’re typically made from carbon steel, stainless steel, or zinc-plated steel. Stainless steel variants offer corrosion resistance for outdoor or humid environments.
