The body of a hex head bolt features external threads that engage with a corresponding nut or a tapped hole, allowing for a secure and adjustable connection. Depending on the intended application, these bolts can be made from various materials, including steel, stainless steel, and even plastic, each offering different levels of strength, corrosion resistance, and weight considerations.

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.

Self-drilling screws, as the name suggests, eliminate the need for a pre-drilled hole, saving significant time and effort in construction, manufacturing, and repair projects. The flat head design of these screws is particularly advantageous as it sits flush with the surface, providing a clean and aesthetic finish. This feature makes them ideal for applications where a smooth surface is crucial, such as in furniture making, automotive repairs, or electronics assembly.

The concept of chemical fixing bolts is rooted in the science of chemistry. They operate on the principle of chemical bonding, where a two-part epoxy resin or other specialist adhesive is used to create a bond between the bolt and the material it's being fixed into. This adhesive, when mixed, undergoes a chemical reaction, hardening and solidifying over time, thereby locking the bolt in place with immense force.
