double end threaded rods and studs

The primary function of a continuously threaded rod lies in its ability to provide tension and compression support in structural systems. In construction, they are commonly used in pre-stressed concrete, where tension is applied before the concrete sets, enhancing its strength and durability. They also find usage in post-tensioning systems, where tension is applied after the concrete has cured, providing additional stability to the structure.

In addition to material selection, the chemical properties of anchor fasteners also play a crucial role in their performance. Various chemical coatings and treatments can be applied to anchor fasteners to improve their strength, durability, and resistance to corrosion. For example, zinc plating is commonly used to protect anchor fasteners from rust and corrosion, extending their lifespan and ensuring long-term reliability

The design of an M8 wedge anchor is simple yet effective. It consists of a threaded rod with a nut and washer, accompanied by a wedge-shaped expansion sleeve. When installed, the anchor is drilled into a pre-drilled hole in the concrete, and then the bolt is inserted and tightened. As the bolt is tightened, it pulls the wedge-shaped sleeve against the sides of the hole, creating friction and causing the sleeve to expand. This expansion locks the anchor securely in place, providing a strong hold that can withstand significant loads.
