Conveyor Belt Fastener is used in underground, open pit mines, docks and other places where conveyor belts are used. It is specifically used to connect and secure fasteners between two belts. Use our Fastener Installation Tools when using. Our Conveyor Belt Fastener is made of high-quality carbon steel. After special process, it refines the internal structure and surface hardening of the material. It has the advantages of high tensile strength, long life, abrasion resistance, corrosion resistance, convenient use and firm connection. Widely used in the connection of conveyor belts such as mines, power plants and ports.
