Screws are fasteners that allow you to join different parts using the thread they have. Commonly made of metal, screws are used to screw and connect components securely. The hardware, consisting of bolts, nuts and collar, provides a robust solution for anchoring. The bolts are screwed through the holes in the parts to be assembled and secured with nuts and ferrules to ensure a strong anchorage. Dowels, used for fixing into masonry, expand when driven into a hole, providing a solid anchor to support loads and structures. Furthermore, the latter are designed to provide an effective and long-lasting traction force.
