The manufacturing process is another critical factor. Full-threaded rods are typically cold-forged or cut from a solid bar. Cold-forging provides better mechanical properties but is more expensive, while cutting from a bar is less costly but may result in a slightly weaker product.

Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them. Typically made from durable plastic, these anchors are inserted into a pre-drilled hole in the wall. When a screw is inserted into the anchor, it pulls the anchor wings outward, gripping the surrounding material tightly. This expansion creates a hold strong enough to support various weights, making them ideal for a wide range of applications.

Indented foundation bolts, also known as anchor bolts, are designed with a unique feature - an indentation or groove on their surface. This indentation serves a dual purpose. Firstly, it increases the surface area in contact with the concrete, thereby enhancing the bond strength between the bolt and the foundation. Secondly, during the tightening process, the indentation acts as a stress concentrator, causing the concrete around it to fracture, creating a mechanical interlock. This mechanism significantly improves the load-bearing capacity and resistance to shear forces.
