Sleeve Anchors
Sleeve Anchors are mechanical expansion fasteners designed for secure anchoring in solid concrete, masonry, brick, and hollow base materials. Unlike wedge anchors, sleeve anchors distribute expansion force along the entire sleeve, making them ideal for medium to heavy-duty fastening applications in construction, railways, and industrial infrastructure.
At Rajal Industries, we manufacture precision-engineered Sleeve Anchors conforming to ASTM, DIN, and ISO standards, ensuring high pull-out resistance, superior load-bearing capacity, and corrosion protection for long-term performance.
Sizes & Standards
| Size Range | Standards |
|---|---|
| Metric: M6 to M24 | DIN 529 – German standard for sleeve-type expansion anchors |
| Imperial: 1/4" to 1" | ASTM E1512 – Standard for mechanical expansion anchors in concrete and masonry |
Material & Strength Grades
| Material Type | Available Strength Grades | Industry Standards |
|---|---|---|
| Carbon Steel & Mild Steel | Class 5.8, 8.8, 10.9 | DIN 529, ASTM E1512 |
| Stainless Steel (Corrosion Resistant) | A2-70 (SS 304), A4-80 (SS 316) | ISO 3506 |
| Hot-Dip Galvanized Steel (Outdoor Use) | Class 8.8, 10.9 | DIN 529, ASTM E1512 |
- Heat-Treated for Maximum Strength –Sleeve anchors undergo quenching and tempering for enhanced tensile strength and impact resistance.
- Load Ratings Based on Material & Application:
- Carbon Steel Class 8.8 Sleeve Anchor: 800-900 MPa tensile strength
- Stainless Steel A4-80 Sleeve Anchor: 700-800 MPa corrosion-resistant strength
Sleeve Anchor Design & Engineering Features
Full-Sleeve Expansion for Secure Anchoring in Weak or Brittle Materials
- The expanding sleeve applies uniform gripping force along the drilled hole, reducing stress on the base material.
- Â
- Ensures strong hold in hollow blocks, lightweight concrete, and brickwork without cracking.
Versatile Through Bolt Design for Various Fastening Needs
- Can be installed directly through the fixture, eliminating extra alignment work.
Available in flat-head, hex-head, round-head, and countersunk options for aesthetic and structural applications.
Heavy-Duty Holding Power & Vibration Resistance
- Designed for seismic, wind-load, and dynamic forces in industrial environments.
Maintains secure fastening in equipment mounting, construction, and mechanical applications.
Corrosion-Resistant Coatings for Long-Term Durability
- Available in zinc-plated, hot-dip galvanized, and stainless steel finishes.
Protects against moisture, chemical exposure, and environmental wear.- Â
- Â
- Â
Pre-Assembled Nut & Washer for Easy Installation
- Reduces installation time and improves efficiency in large-scale projects.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/Metric) | Ensures fast engagement and strong grip | Concrete, masonry, brickwork |
| Fine Thread (UNF/Metric Fine) | Provides higher tensile strength & precise load transfer | Seismic zones, railway fastening |
| Fully Threaded Sleeve Anchors | Allows maximum adjustability and secure fastening | Industrial structures, HVAC, and MEP systems |
| Partial Thread Sleeve Anchors | Offers better shear strength & enhanced load distribution | Bridges, high-rise buildings, and scaffolding |
Thread Fitment & Compliance
- Metric threads conform to ISO 6H tolerances, ensuring secure engagement with pre-drilled holes.
- Imperial sleeve anchors meet ASTM E1512 for universal compatibility in construction and industrial applications.
