Hollow Wall Anchor

Welcome to the Hollow Wall Anchors category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your specialized manufacturer and global supplier located in Handan Yongnian, the largest fastener production base in China. Building on our technical heritage as the former Yonghong expansion screw factory, we produce high-performance hollow wall anchors—also known as cavity anchors or umbrella bolts—specifically engineered for secure fastening in plasterboard, plywood, and other hollow substrates. Our hollow wall anchors are precision-manufactured to comply with international standards, including GB, DIN, ANSI, and BS, ensuring seamless compatibility for global interior fit-out projects. Fabricated from high-grade Carbon Steel and available in Stainless Steel (SS304/SS316), these fasteners are designed to expand behind the base material to provide a large load-bearing surface area. To guarantee exceptional durability and protection against environmental corrosion in indoor settings, our products feature professional surface treatments such as White Zinc Plating and Yellow Zinc Plating. Designed for both light and medium-duty applications, such as hanging mirrors, shelving, and curtain rails, our anchors provide high pull-out resistance and permanent internal threads for easy bolt removal. With our advanced factory-direct production lines, we offer a full range of metric sizes and can accommodate custom manufacturing requirements based on your unique engineering blueprints. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and performance demands of modern global construction.
