The 'hex bolt' portion signifies the threading on the bolt's shank, which extends from under the head to the tip. This thread is what engages with the mating female thread in the component being fastened, creating a secure joint. The thread pitch and diameter are crucial factors determining the bolt's load-bearing capacity and compatibility with different materials The thread pitch and diameter are crucial factors determining the bolt's load-bearing capacity and compatibility with different materials The thread pitch and diameter are crucial factors determining the bolt's load-bearing capacity and compatibility with different materials The thread pitch and diameter are crucial factors determining the bolt's load-bearing capacity and compatibility with different materialshead hex bolt.

Shear connector studs, typically made from high-strength steel, are installed vertically in the composite section before the concrete is poured. They serve as a mechanical link, facilitating the transfer of shear and tensile forces between the steel and concrete components. This connection is crucial, especially in structures subjected to dynamic loads such as earthquakes or high winds, where the ability to resist shear forces is paramount.

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.
