Shear studs are typically welded to the steel section of a composite beam before concrete is poured. Their primary function is to transmit shear forces between the steel and the concrete, preventing the two components from sliding apart under load. This connection enhances the load-carrying capacity of the beam and allows for a more efficient use of materials, ultimately leading to lighter and more cost-effective structures.

Countersunk self-drilling screws are a specific type of screw designed to allow for a flush finish in various materials, including wood, metal, and plastic. The term countersunk refers to the conical shape of the screw head, which allows it to sit seamlessly against the surface of the material being fastened.
