Expansion Screw Bolts - Material and durability: made of 304 stainless steel, these anchors are waterproof, abrasion resistant, and durable in challenging environments. - Load bearing performance: each bolt can bear up to 50 kg, providing a strong, reliable mounting solution for medium to heavy fixtures. - Easy installation: drill a hole in the wall, insert the expansion screw into the hole, then tighten the nut on the outside of the wall to activate the expansion sleeve. - Compatibility and application: suitable for use in concrete and masonry surfaces, ideal for securing fixtures that require a solid hold. - Size options: available in multiple sizes to fit different fixtures and load requirements. - Practical applications: can be used for mounting canopy or awning brackets to exterior walls, securing water heater installations, fixing air conditioning brackets, and various home decoration or industrial engineering projects. - How it works: tightening the nut expands the inner sleeve against the wall, creating a firm grip that resists pull-out and maintains a stable attachment. Use scenarios - Mounting a canopy to a concrete exterior wall to provide a secure overhead shelter. - Fixing a water heater bracket or mounting hardware to masonry or concrete surfaces for a stable installation. - Attaching air conditioning unit brackets to a solid concrete or masonry base to ensure safe, compliant support.
