Heavy-duty double stud fittings are constructed for withstanding extreme loads. They are made from high-grade alloy steels which offer great strength and durability. Such fittings are used with many industries including construction, heavy equipment manufacturing, and large scale logistics. For instance, these can be used in construction sites to attach trailers to great vertex machinery components. Their design incorporates precision threaded studs and bases that are reinforced which helps provide a secure and permanent bond even in severe environments.
