The Screw-In Anchor Back Bolt TUB-X is a professional fastening solution engineered for high-reliability anchoring needs. It consists of two main configurations: one includes a screw, expansion head, and flange nut, while the two-piece back bolt variant comprises an expansion head and flange screw. Crafted from premium materials—including 304(A2) stainless steel, 316(A4) stainless steel, and 210 stainless steel—this anchor bolt is designed to handle heavy-duty applications, making it ideal for projects requiring long-term stability, such as building curtain walls, industrial equipment installation, and interior decoration. Its robust structure and versatile design ensure compatibility with diverse substrates, even in demanding environments.

The Screw-In Anchor Back Bolt TUB-X boasts exceptional High Load Capacity, thanks to its sturdy construction that enables it to bear substantial weights without compromising stability. Moreover, it delivers superior Seismic Performance, maintaining structural firmness in earthquake-prone regions. This feature is critical for ensuring the safety of buildings and equipment during dynamic loads, reducing the risk of anchorage failure.
A key advantage of this anchor bolt is its Zero Expansion Stress during installation. Unlike traditional expansion anchors that may cause cracking or weakening, this design prevents damage to the substrate, preserving the original structure’s integrity and extending its service life. It is particularly suitable for delicate or sensitive substrates (e.g., thin concrete panels) where substrate protection is paramount.
The Screw-In Anchor Back Bolt TUB-X supports Quick Installation, with a straightforward process that reduces labor time and costs. Post-installation, it offers easy Adjustability, allowing precise positioning to meet specific project requirements. This flexibility makes it adaptable to scenarios where accuracy is critical, such as aligning curtain wall panels or securing industrial machinery.
Made from 304(A2)/316(A4)/210 stainless steel, the anchor bolt exhibits outstanding Durability. It withstands prolonged exposure to moisture, chemicals, and extreme temperatures, minimizing the need for frequent replacements. Additionally, its low maintenance nature cuts long-term upkeep expenses, delivering cost savings over the product’s lifecycle.
