Hex self-tapping screws are typically made from durable materials such as stainless steel, carbon steel, or other alloys, enhancing their strength and resistance to corrosion. Available in various sizes and thread patterns, these screws can accommodate different materials, including wood, metal, plastic, and composite materials.

5. Precast Elements M20 bolts are used to connect precast concrete elements during assembly, providing quick and effective ways to join large structures without extensive welding or other complex methods.

One of the primary advantages of double end threaded rods is their ability to facilitate the connection of two non-threaded components. This feature makes them particularly useful in situations where a secure, yet adjustable joint is required. For example, in construction, double end threaded rods can be used to join metal beams, allowing for flexible arrangements of structural elements without the need for additional fixtures. Their design allows for easy adjustments, making it simple to achieve the desired tension or alignment.

Chemical anchors consist of a resin or adhesive that, when mixed with a hardening agent, polymerizes to form a strong bond with the base material. These anchors are typically used in conjunction with metal rods or bolts that are inserted into drilled holes. The chemical reaction that occurs once the resin is mixed makes the bond resistant to shear and tensile stress, significantly outperforming traditional anchoring solutions in many scenarios.
