self drilling bolts for steel

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.

The designation 1% 4% 2014 typically reflects specific characteristics associated with the screw's design and material composition, indicating its strength and suitability for particular applications. In many cases, the numbers denote the alloying elements in the screw's material, particularly in the context of steel to enhance corrosion resistance and overall durability. For instance, 1% might refer to the percentage of a certain alloy, while 4% could represent a different additive, both contributing to the screw's ability to withstand environmental stresses.
