Versatile M6-M24 Sleeve Anchors for Concrete and Masonry

Our Sleeve Anchors are the ideal solution for light to heavy-duty fastening in both solid and hollow base materials. Unlike standard wedge anchors, the sleeve expansion bolt features a full-length expansion sleeve that distributes the load evenly across the hole, making it safer for use in older concrete or masonry applications.

Whether you are securing window frames, handrails, or heavy racking, these Expansion Sleeve Bolts offer a reliable and cost-effective anchoring solution with minimal edge distance requirements.

Available Head ConfigurationsWe supply Sleeve Anchors in various designs to match your specific fixture needs:

  • Hex Nut Type: The standard choice for heavy-duty structural fixings.
  • Flange Nut Type: Provides a larger surface area for better clamping force.
  • Hook & Eye Type: Specialized for securing cables, chains, and sunshades.
  • Countersunk (Flat Head): Ideal for flush-mount installations like door and window frames.

Easy Installation Process

  1. Drill: Use a hammer drill to create a hole (the drill bit size should match the anchor’s outside diameter).
  2. Clean: Blow out the dust and debris from the hole.
  3. Insert: Drive the sleeve anchor through the fixture into the hole until the washer is flush against the material.
  4. Tighten: Tighten the nut or screw. This pulls the cone into the sleeve, expanding it firmly against the hole wall.
