1. Look at the concrete wedge anchors material
High-quality wedge anchor bolts should be made of high-strength steel. Although iron expansion screws are cheap, they are easy to rust: stainless steel wedge anchor have better anti-rust performance. When choosing, you should choose the right material according to your actual needs and uses
2. concrete wedge anchor expansion tube thickness and screw matching degree
good expansion screw expansion tube is thicker and cannot be pinched by hand, which can greatly increase the anchoring force in the wall. At the same time, good trubolt wedge anchor have a high degree of matching with nuts, and will not cause scratches during installation, and safety and quality are also guaranteed
3. The higher the thread accuracy, the better the sealing performance of the wedge anchor / thru bolt
bolt wedge anchor tensile strength and car trimming force strength: these two parameters can reflect the bearing capacity of the wej ankr.
The types of through bolt are used in different occasions.
concrete wedge anchor installation and maintenance: Correct installation and maintenance are the key to ensuring that the expansion screws work. During installation, follow the steps in the instructions to ensure that the length of the screw matches the object to be fixed. At the same time, when using power tools to rotate the screws, keep the speed constant to avoid excessive force that may cause the screws to break. During use, check the status of the expansion screws regularly. If they are found to be loose or damaged, they should be maintained or replaced in time.
