Sleeve Anchor Bolt — Heavy Duty Expansion Type

Description

1. Product Overview

The Sleeve Anchor Bolt — Heavy Duty Expansion Type is a high-strength mechanical fastener engineered for secure anchoring in concrete, masonry, and brick substrates. It is primarily used in industrial construction, infrastructure projects, and heavy equipment mounting where reliable load-bearing capacity is critical. The key value proposition lies in its robust expansion mechanism, which delivers superior tensile and shear strength compared to standard anchors. Strategically, this product is essential for enterprises seeking durable, code-compliant fastening solutions that minimize failure risk in demanding environments.

2. Key Specifications & Technical Characteristics

• Grade/Purity: Industrial-grade metallurgy meeting DIN, ANSI, GB, JIS, ASME, BS, EN standards

• Physical Characteristics:

  • Form: Hexagon head bolt with expansion sleeve, plastic ring, and cone nut

  • Diameter: M6–M20 (φ8.0 mm–φ20 mm); custom sizes M1–M120 available

  • Length: 50–300 mm (standard); non-standard lengths on request

  • Surface Finish: Zinc-plated for rust resistance

  • Tensile Capacity: Up to 120 kN

• Packaging Options: Bulk cartons, palletized bundles, or custom packaging per buyer requirement

• Shelf Life: Indefinite when stored in dry conditions (zinc plating prevents corrosion)

3. Core Industrial Applications

• Primary Industries:

  • Building & construction (structural framing, façade anchoring)

  • Infrastructure (bridges, tunnels, retaining walls)

  • Heavy industrial (machinery mounting, steel structure assembly)

  • Energy sector (solar panel racking, wind turbine components)

• Operational Use Cases:

  • Wall, floor, and ceiling fixing for beams, columns, and equipment

  • Anchoring HVAC systems, conveyor belts, and safety railings

  • Securing modular prefabricated structures

• Performance Advantages:

  • Delivers higher load capacity than wedge anchors or drop-in anchors in hollow-base materials

  • Simple drill-and-insert installation reduces labor time by 30–40%

  • Expansion sleeve provides uniform clamping force, minimizing substrate cracking
