The Φ30-34 expansion bolt and Ordinary expansion 8x150 are heavy-duty anchoring solutions designed for industrial applications such as structural installations, machinery mounting, and construction projects. The Φ30-34 expansion 8x150 variant features a robust Φ30-34mm diameter bolt paired with an 8x150mm expansion sleeve, providing high tensile strength (up to 35kN static load) and vibration resistance. Constructed from galvanized carbon steel, it operates reliably in temperatures from -20°C to 120°C and requires a 34-36mm drill hole for installation. While its large size ensures exceptional load-bearing capacity in concrete or masonry, the installation demands precise alignment and specialized tools. The ordinary 8x150mm model offers a compact alternative for lighter applications but with reduced torque tolerance. Both versions lack integrated connectivity but are compatible with standard industrial fastening systems. Key advantages include corrosion resistance and adaptability to uneven surfaces, though their bulkiness may limit use in confined spaces.
