Iron Expansion Bolts for Hollow Bricks1

Our High Strength Iron Expansion Bolt for Hollow Bricks is specially designed for secure fixing applications in hollow brick walls, lightweight blocks, and masonry structures. Manufactured from high-quality iron material, this expansion bolt provides strong holding force, reliable stability, and excellent load-bearing performance for construction and installation projects.

The special expansion structure allows the anchor to expand inside hollow materials, creating a secure connection without damaging the wall structure. As a professional Fastener Manufacturer, we provide a wide range of fastening solutions, including expansion bolts, anchors, screws, bolts, nuts, and customized Industrial Fasteners for global distributors and construction companies.

Made from durable iron material, the expansion bolt provides excellent mechanical strength and deformation resistance.

The Iron Expansion Bolt is suitable for medium and heavy-duty fastening applications requiring reliable fixing performance.

Designed with an optimized expansion structure, the product expands inside hollow wall cavities to create a strong anchoring point. As a professional Fastener Manufacturer, we supply a wide range of fastening solutions including anchors, screws, bolts, and customized Construction Fasteners for global distributors and engineering projects.

Manufactured from high-quality iron and carbon steel materials, this expansion screw features excellent strength, stable performance, and cost-effective installation advantages. The zinc plated surface improves corrosion resistance and extends service life in indoor applications.

This product is widely used by building material wholesalers, hardware distributors, construction suppliers, and OEM customers requiring bulk supply of reliable wall anchoring solutions.

• The High Strength Iron Expansion Bolt for Hollow Bricks is widely used in:

  • Building construction
  • Interior decoration projects
  • Electrical equipment installation
  • HVAC system installation
  • Wall-mounted equipment fixing
  • Furniture installation
  • Engineering maintenance projects

  As an important product among Construction Fasteners, it provides reliable fixing solutions for professional and DIY applications.

• OEM and ODM customization available

• When tightened, the expansion sleeve expands inside the wall cavity, creating a strong mechanical lock.

  The Expansion Anchor Bolt provides secure fastening for construction, decoration, equipment installation, and engineering applications.

• Precision Iron Expansion Screws for Hollow Walls are manufactured through metal forming, thread processing, surface treatment, and assembly procedures. The production process ensures accurate dimensions, smooth threads, and consistent expansion performance.

  The expansion sleeve design allows the anchor to expand behind hollow wall panels when the screw is tightened. This creates a larger contact area and improves load distribution, making it suitable for mounting lamps, shelves, cabinets, electrical equipment, decorative panels, and other indoor fixtures.

  The iron carbon steel structure provides sufficient mechanical strength for daily fixing applications. Zinc plated coating protects the surface from oxidation and improves durability under normal indoor conditions.

  During production, each batch is inspected through material checking, dimensional measurement, thread inspection, expansion performance testing, and surface quality inspection. Strict quality control ensures stable product performance for international wholesale supply.

  Customization options include size, screw type, surface finish, packaging design, and private label solutions. The factory supports bulk production for distributors, construction suppliers, and OEM customers.
